Description

Technical Field

[0001] The present invention relates to the field of water treatment equipment, and specifically to a water purifier integrating automatic cleaning, sterilization and activation functions, which is used in various water treatment scenarios such as drinking water, mineral water and tap water. Background Art

[0002] As a common household or commercial device, the core function of a water purifier is to remove impurities, microorganisms, and harmful substances from water. The technical defects of traditional water purifiers are mainly concentrated in the following: (1) Filter element contamination and secondary pollution problems: Filter elements are easy to clog: After long-term use, filter elements (such as PP cotton, activated carbon, RO membrane) will accumulate impurities, resulting in reduced water flow and reduced filtration efficiency. Bacterial growth: The moist environment of the filter element is prone to the growth of bacteria (such as E. coli and Legionella), causing the output water microorganisms to exceed the standard. Manual cleaning is inconvenient: Traditional cleaning requires disassembly of the machine and replacement of the filter element, which is complicated for users and may damage the equipment. (2) Insufficient sterilization function: Single ultraviolet sterilization or chemical disinfection (such as ozone) has limitations: ultraviolet rays require long-term exposure and are ineffective against certain viruses; chemical disinfection may leave residual byproducts (such as bromate). Some water purifiers do not have a continuous sterilization function and rely only on filtration, which cannot deal with secondary pollution in the pipeline. (3) Lack of water activation technology: Traditional water purifiers only focus on "purification" and ignore the health of drinking water: demineralized water tastes poor; there is a lack of activation technology (such as electrolysis, magnetization) to improve the solubility and permeability of water.

[0003] To address these issues, automated cleaning methods such as backwashing (e.g., using high-pressure water to clean RO membranes) or pulse cleaning have been proposed. However, these methods fail to completely remove biofilms, resulting in incomplete cleaning. Sterilization methods have combined ultraviolet light with photocatalysis (TiO2) and silver ion antibacterial agents, but these methods are costly and lack durability.

[0004] In summary, existing water purifiers have problems such as incomplete automatic cleaning, high sterilization costs, or poor durability. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems of incomplete automatic cleaning, high sterilization cost or poor durability of existing water purifiers, and further provide a water purifier that integrates automatic cleaning, sterilization and activation functions.

[0006] The technical solution of the present invention is:

[0007] A water purifier integrating automatic cleaning, sterilization and activation functions includes a shell, a central control board, a drive board, a filter element assembly, an ultrasonic cleaning device and a pulse sterilization system. The central control board is mounted on the side end face of the shell, the drive board is mounted on the inner side wall of the shell, the filter element assembly is mounted inside the shell, and the ultrasonic cleaning device and the pulse sterilization system are respectively mounted on the bottom of the filter element of the filter element assembly to achieve sterilization of the water in the filter element and cleaning of the filter element.

[0008] Preferably, the housing is a rectangular stainless steel shell.

[0009] Furthermore, the filter element assembly includes a support frame, a valve head, an elbow, a pre-filter element assembly and a post-carbon filter element. The support frame is horizontally installed in the outer shell, the valve head is installed on the lower end surface of the support frame, the pre-filter element assembly is installed at the lower part of the support frame and connected to the valve head, the post-carbon filter element is installed at the upper part of the support frame, and the post-carbon filter element and the valve head are connected through an elbow.

[0010] Furthermore, the support frame is a plate body with openings at both left and right ends. The support frame is horizontally installed in the shell and connected to the inner wall of the shell.

[0011] Furthermore, the pre-filter element assembly includes a PP cotton filter element, a granular carbon filter element, a sintered carbon filter element and an ultrafiltration filter element. The PP cotton filter element, the granular carbon filter element, the sintered carbon filter element and the ultrafiltration filter element are arranged vertically and in sequence from right to left, and the upper parts of the PP cotton filter element, the granular carbon filter element, the sintered carbon filter element and the ultrafiltration filter element are all connected to the valve head.

[0012] Furthermore, an ultrasonic cleaning device is installed at the lower end of the ultrafiltration filter element, and a sewage outlet is opened at the lower part of the ultrafiltration filter element, and a pulse sterilization system is installed at the lower end of the PP cotton filter element.

[0013] Furthermore, it also includes a solenoid valve, which is installed in the shell. One end of the sewage pipe body is connected to the sewage outlet, and the other end of the sewage pipe body is connected to one end of the solenoid valve, and after passing through the solenoid valve, it is connected to the sewage outlet installed on the shell through another sewage pipe body.

[0014] Furthermore, it also includes a water inlet pipe, one end of which is connected to the water inlet pipe port installed on the shell, and the other end of the water inlet pipe is connected to the end of the valve head.

[0015] Furthermore, it also includes a purified water pipe, one end of which is connected to the water outlet of the post-carbon filter element, and the other end of which is connected to the purified water pipe port installed on the shell.

[0016] Preferably, it further comprises a water activator, which is installed on the purified water pipe.

[0017] Compared with the prior art, the present invention has the following effects:

[0018] 1. The water purifier of the present invention incorporates an ultrasonic cleaning device A and a pulse sterilization system B on the filter element assembly. Upon receiving a signal from a hollow plate, the ultrasonic cleaning device A activates a drive plate to operate a transducer within the ultrasonic cleaning device A, located at the lower end of the ultrafiltration filter element 7. The transducer cleans the filter element within the ultrafiltration filter element 7, and the cleaned wastewater is discharged through a drain pipe under the action of a solenoid valve 13. The ultrasonic cleaning device A of the present invention is based on the principle of cavitation: during the cleaning process, ultrasonic pulses rapidly form and instantly implode a large number of bubbles within the cleaning fluid, generating an impact force that can dislodge dirt from the workpiece surface. High-frequency ultrasound is particularly suitable for cleaning small particles without damaging the workpiece surface. Compared to traditional cleaning methods, ultrasonic pulse cleaning offers significant advantages, including excellent cleaning effectiveness, high speed, no damage to the workpiece, and solvent savings. It is particularly suitable for cleaning components with complex surface structures and high cleanliness requirements. In this water purifier, this system is used to clean the water storage tank and filter element, successfully resolving the problem of difficult filter element cleaning.

[0019] 2. The pulse sterilization system B of the present invention controls the start and stop of sterilization by turning on or off the water flow switch, and sterilizes at high temperature using the transducer in the pulse sterilization system B. The sterilization principle is: utilizing the reagent-free and highly ecological sterilization characteristics of ultrasonic pulses, during the water purification process, through mechanisms such as free radical reactions generated by cavitation, the bacteria and organic pollutants in the water are oxidatively destroyed. Combined with technologies such as ozonation, it can achieve a more outstanding synergistic sterilization and purification effect, effectively overcoming the problem of incomplete sterilization in traditional water dispensers, and effectively ensuring the safety of drinking water. In addition, since the pulse sterilization system B of the present invention is combined with ozonation technology, the service life of the water purifier is increased, the durability is better, and the production and use costs are reduced.

[0020] 3. The present invention is equipped with a water activator on the purified water pipe, which can activate the water. The treated small molecule water has a variety of properties beneficial to the human body, such as regulating the pH of body fluids, scavenging free radicals, lowering blood lipids, etc., which greatly improves the quality and health value of drinking water.

[0024] The use of ultrasonic cleaning device A in this embodiment significantly improves cleaning effectiveness, solving filter element cleaning challenges and significantly reducing filter element replacement frequency, thereby lowering operating costs. Compared to traditional cleaning methods, ultrasonic cleaning efficiency is increased several times, even dozens of times, achieving higher cleanliness standards.

[0025] In addition, the sterilization effect of the present invention is more thorough: it overcomes the disadvantage of incomplete sterilization of traditional water dispensers, utilizes the sterilization characteristics of ultrasonic pulses, and combines possible combination technologies to effectively ensure the safety of drinking water and greatly reduce the harm of bacteria to human health.

[0026] The central control panel 2 of this embodiment is a display and has control buttons for users to select the appropriate cleaning or sterilization time according to their actual needs. It is more flexible and convenient to use, and realizes automatic cleaning and sterilization. It avoids the problem of traditional water purifiers requiring manual replacement of filter cartridges at regular intervals (e.g., every six months), making it more convenient for users.

[0027] Specific implementation method 2: Combination Figure 1 This embodiment describes the housing 1 as a rectangular stainless steel shell. This design extends the lifespan of the stainless steel shell, particularly preventing rust and corrosion during long-term use, and makes it easier to maintain. The rectangular shape occupies less space and offers a controllable thickness. Other components and connections are identical to those in the first embodiment.

[0028] The shell 1 of this embodiment is provided with chamfers on all four sides. In addition, grooves are provided on the inner side walls of the shell 1 of this application. The grooves are mainly used for routing the lines involved in the circuit board on the central control board 2 and the wires on the driving board 3, ensuring the safe and reliable operation of the internal electronic control part of the water purifier, facilitating maintenance, and the lines are regular.

[0029] Specific implementation method three: Combination Figure 1To describe this embodiment, the filter element assembly of this embodiment includes a support frame 9, a valve head 10, an elbow 11, a pre-filter element assembly and a post-carbon filter element 8. The support frame 9 is horizontally installed in the housing 1, the valve head 10 is installed on the lower end surface of the support frame 9, the pre-filter element assembly is installed at the lower part of the support frame 9 and is connected to the valve head 10, the post-carbon filter element 8 is installed at the upper part of the support frame 9, and the post-carbon filter element 8 and the valve head 10 are connected through the elbow 11.

[0030] In this way, the impurities in the water are filtered one by one by the pre-filter assembly, and then filtered again by the post-carbon filter 8, so as to ensure the quality of the water. The other components and connection relationships are the same as those of the specific embodiment 1 or 2.

[0031] The valve head 10 in this embodiment is preferably a plastic valve head, which is easy to clean and not prone to corrosion.

[0032] In actual use, the elbow 11 in this embodiment is preferably made of stainless steel, which is not easy to rust and is convenient for ensuring the quality of the output water.

[0033] Specific implementation method four: Combination Figure 1 To describe this embodiment, the support frame 9 of this embodiment is a plate with openings at both ends. The support frame 9 is horizontally installed in the housing 1 and connected to the inner wall of the housing 1.

[0034] With this arrangement, the support frame 9 is primarily used to mount the pre-filter element assembly and the post-carbon filter element 8. The valve head 10 is mounted on the support frame 9, and the upper end of the support frame 9 provides a support for mounting the post-carbon filter element 8. The remaining components and connections are the same as those in any one of the first to third embodiments.

[0035] In this embodiment, the left and right ends of the support frame 9 are provided with openings, which can reduce the weight of the entire water purifier and ensure that the stainless steel elbow and other wires can pass through smoothly, making it more flexible and convenient to use.

[0036] Specific implementation method five: Combination Figure 1 To illustrate this embodiment, the pre-filter element assembly of this embodiment includes a PP cotton filter element 4, a granular carbon filter element 5, a sintered carbon filter element 6 and an ultrafiltration filter element 7. The PP cotton filter element 4, the granular carbon filter element 5, the sintered carbon filter element 6 and the ultrafiltration filter element 7 are arranged vertically and in sequence from right to left, and the upper parts of the PP cotton filter element 4, the granular carbon filter element 5, the sintered carbon filter element 6 and the ultrafiltration filter element 7 are all connected to the valve head 10.

[0037] In this way, the four groups of filter elements are arranged in sequence according to the size of the impurity particles that can be filtered out, thereby ensuring the filtering effect. The other components and connection relationships are the same as any one of the specific embodiments 1 to 4.

[0038] The lower portion of the ultrafiltration filter element 7 of this embodiment is further provided with two connection terminals for connecting to the circuit in the driving board 3 , so as to facilitate driving the ultrasonic cleaning device A at the lower portion of the ultrafiltration filter element 7 through the driving board 3 for ultrasonic cleaning.

[0039] The PP cotton filter element 4, granular carbon filter element 5, sintered carbon filter element 6, ultrafiltration filter element 7 and post-carbon filter element 8 in this embodiment are detachably installed with multiple slots on the end face of the shell 1 during the actual installation process. A filter element is mounted on each slot, making the installation of the filter element more stable.

[0040] Specific implementation method six: combination Figure 1 To illustrate this embodiment, the ultrasonic cleaning device A of this embodiment is installed at the lower end of the ultrafiltration filter element 7, and a sewage outlet 12 is opened at the lower part of the ultrafiltration filter element 7, and the pulse sterilization system B is installed at the lower end of the PP cotton filter element 4.

[0041] In this arrangement, since the filtration aperture of the ultrafiltration filter element 7 is very small, many traditional methods of cleaning the filter element cannot completely clean it. However, this embodiment uses ultrasonic cleaning to completely clean the filter element. The other components and connection relationships are the same as any one of the specific embodiments 1 to 5.

[0042] Specific implementation method seven: combination Figure 1 To illustrate this embodiment, this embodiment also includes a solenoid valve 13, which is installed in the shell 1. One end of the sewage pipe body is connected to the sewage outlet 12, and the other end of the sewage pipe body is connected to one end of the solenoid valve 13. After passing through the solenoid valve 13, another sewage pipe body is connected to the sewage outlet 14 installed on the shell 1.

[0043] In this configuration, the electromagnetic valve 13 is used to discharge the wastewater after ultrasonic cleaning in the ultrafiltration filter element 7. Other components and connection relationships are the same as those in any one of the specific embodiments 1 to 6.

[0044] The solenoid valve 13 of this embodiment is preferably installed at the inner bottom of the housing 1 below the granular carbon filter element 5 and the sintered carbon filter element 6 .

[0045] Specific implementation method eight: combination Figure 1 This embodiment also includes a water inlet pipe, one end of which is connected to the water inlet port 15 mounted on the housing 1, and the other end of which is connected to the end of the valve head 10. This arrangement allows the water inlet pipe to fill the pre-filter assembly and post-carbon filter 8 with water, which then filters out impurities through the pre-filter assembly. The remaining components and connections are identical to those of any of the first through seventh embodiments.

[0046] Specific implementation method nine: combination Figure 1This embodiment also includes a purified water pipe, one end of which is connected to the water outlet of the post-carbon filter element 8, and the other end of which is connected to the purified water pipe port 16 mounted on the housing 1. This arrangement allows the purified water to be discharged. The remaining components and connections are the same as those of any of the first to eighth embodiments.

[0047] Specific implementation method ten: Combination Figure 1 To illustrate this embodiment, this embodiment also includes a water activator, which is installed on the purified water pipe. So configured, the water activator in this embodiment is composed of a signal generator and a pipeline coil. The signal generator sends out a complex changing signal to generate an electromagnetic field in the pipeline, causing the water molecules to resonate and converting hydrogen-bonded water molecule clusters into single polar water molecules. The treated small molecule water has beneficial properties for the human body, such as regulating the pH of body fluids, scavenging free radicals, and lowering blood lipids, thereby improving the quality and health value of drinking water. The signal generator can automatically adjust the output signal frequency and intensity according to parameters such as water flow and water hardness to ensure the best activation effect under different working conditions. The other components and connection relationships are the same as any one of the specific embodiments one to nine.

[0048] The pipe coil in this embodiment uses a multi-strand fine wire winding process to ensure a uniform and stable electromagnetic field. The number of coil turns and winding method are precisely calculated and experimentally verified to achieve the best water activation effect.

[0049] Combine Figure 1 The working principle of the present invention is described:

[0050] Cleaning operation:

[0051] After the water purifier has been running for a period of time, the user can set the cleaning time and frequency according to actual conditions, or choose automatic cleaning mode (the device automatically determines whether to clean based on parameters such as the filter usage time and water quality).

[0052] After the cleaning process is initiated via central control board 1, the ultrasonic pulse generator in driver board 2 sends a high-frequency oscillation signal to the transducer, which converts it into mechanical vibrations and transmits them into the cleaning fluid. The cleaning fluid is sprayed onto the filter surface through a nozzle. Under the action of ultrasound, bubbles implode, peeling off dirt, and the wastewater is discharged through the drainage pipe.

[0053] After cleaning is completed, the system automatically stops running and feedback of the cleaning results is given through the display or indicator light.

[0054] Sterilization and activation process:

[0055] During normal water production, the water first flows through the ultrasonic pulse sterilization system B, which utilizes the sterilization effect of ultrasonic pulses and free radical reaction mechanisms, combined with possible auxiliary sterilization technologies such as ozonation, to oxidize and destroy bacteria and pollutants in the water.

[0056] Subsequently, when the water passes through the small molecule water activator, the electromagnetic field causes the water molecules to resonate, transforming from large molecular clusters to small molecule water. The user then uses the activated small molecule water. Water treated by the small molecule water activator possesses a variety of beneficial properties, such as regulating body fluid pH and lowering blood lipids. This helps improve human health and significantly enhances the quality and health benefits of drinking water.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
