Technical Field

[0001] This application relates to the technical field of disinfection equipment for domestic water tanks, and more particularly to a disinfection device and water system. Background Technology

[0002] A water tank is a water storage container that provides water for people's daily life. It is a kind of transfer reservoir used to store and regulate water from municipal pipe networks or other water sources (such as deep well pumps) before distributing it to various water points in a building through pipelines.

[0003] Water in water tanks sometimes remains stagnant for extended periods, leading to contamination by various microorganisms and bacteria. Therefore, it is essential to disinfect the water properly and clean it regularly.

[0004] However, current technology cannot adequately disinfect water tanks. Utility Model Content

[0005] This application provides a disinfection device and a water system to solve the problem that existing technologies cannot adequately disinfect water tanks.

[0008] The water inlet of the storage structure is connected to the water outlet of the water tank through the water inlet pipe, and the water outlet of the storage structure is connected to the water return end of the water tank through the water return pipe.

[0012] In some embodiments of this application, at least one of the inlet pipe and the return pipe is equipped with a booster pump;

[0013] The booster pump is used to drive the water in the water tank to flow along the water inlet pipe to the storage structure, and can also drive the water in the return pipe to flow to the water tank.

[0039] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0040] As mentioned in the background section, stagnant areas in the water tank become breeding grounds for microorganisms and algae. The combined effects of water temperature, light (if there are light-transmitting holes), and nutrients (from pipe corrosion or air) accelerate biofilm formation, causing the water quality to fail to meet hygiene standards and resulting in secondary pollution of the tank water. To eliminate secondary pollution, appropriate disinfection and regular cleaning of the water are necessary. However, current manual disinfection methods are cumbersome, expensive, and sometimes require water outages, causing inconvenience to users.

[0041] Existing water tank disinfection devices are generally installed within the water level of the tank, utilizing the static pressure generated by the water level itself or the pressure from the inlet pipe to force the disinfectant into the tank. The device must be installed immediately adjacent to the tank's inlet or directly submerged in the tank. If the tank is large or has multiple compartments, a single dosing point cannot ensure even distribution of the disinfectant throughout the tank, resulting in disinfection dead zones. In many high-rise buildings, water first enters an underground water tank and is then pumped to a rooftop tank. This underground water tank is located on the pump's suction side and is under negative or zero pressure. In this situation, disinfection devices relying on inlet pressure cannot add disinfectant because the external atmospheric pressure is higher than the internal pressure. Disinfectant (such as ozone) requires gas to overcome water pressure to dissolve, which is impossible in a negative pressure zone. Therefore, existing disinfection devices cannot adequately disinfect the water tank.

[0042] In view of this, the embodiments of this application provide a disinfection device and a water system. By setting an external disinfection component, it ensures that the disinfectant can be smoothly added under any pressure conditions, so that the water tank can be thoroughly disinfected. The return water pipe achieves uniform distribution of the disinfectant throughout the water tank, preventing the growth of microorganisms and algae. It avoids the cumbersome, expensive and inconvenient water outages of traditional manual disinfection measures. The automated disinfection process improves the convenience and economy of operation, while reducing the impact on users' daily water use. The setting of external disinfection components reduces the complexity of device installation and maintenance, and does not require close contact with the water tank inlet or immersion in the water tank, thus expanding the applicable scenarios.

[0043] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0044] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0045] refer to Figure 1 This application provides a disinfection device, including a disinfection component 100, an inlet pipe 200, and an outlet pipe 300.

[0046] The disinfection component 100 is installed on the outside of the water tank 001. The disinfection component 100 includes a generator 110 and a storage structure 120. The generator 110 can provide disinfectant to the storage structure 120.

[0047] The water inlet of the storage structure 120 is connected to the water outlet of the water tank 001 through the water inlet pipe 200, and the water outlet of the storage structure 120 is connected to the water return end of the water tank 001 through the water return pipe 300.

[0048] The storage structure 120 can output disinfectant into the return water pipe 300 so that the disinfectant flows into the water tank 001 through the return water pipe 300.

[0049] It is known that generator 110 can produce substances required for disinfection, such as ozone or other chemical disinfectants, and deliver the disinfectant to storage structure 120.

[0050] Storage structure 120 serves as a temporary storage location for disinfectants, ensuring that the disinfectants are effectively controlled before being added to water tank 001.

[0051] The water inlet pipe 200 connects the water inlet of the storage structure 120 to the water outlet of the water tank 001, and its function is to introduce water from the water tank 001 into the storage structure 120. Through this connection, the water in the water tank 001 can be guided to the external disinfection component 100 for treatment, avoiding the limitation of traditional devices that must be installed close to the inside of the water tank 001 or the water inlet.

[0052] The return water pipe 300 connects the outlet of the storage structure 120 to the return water of the water tank 001. The storage structure 120 outputs disinfectant to the water tank 001 through the return water pipe 300, ensuring that the disinfectant can circulate with the water flow to all areas of the water tank 001, thereby eliminating disinfection dead spots.

[0053] This application overcomes the difficulties of adding disinfectant under negative pressure or zero pressure environments, as well as the problem of uniform distribution of large-capacity water tanks 001 or multi-compartment water tanks 001, by setting the disinfection component 100 on the outside of the water tank 001 and using the inlet pipe 200 and return pipe 300 to realize water circulation and disinfectant addition.

[0054] By installing an external disinfection component 100, the disinfectant can be smoothly added under any pressure conditions, ensuring thorough disinfection of the water tank 001. The return water pipe 300 ensures uniform distribution of the disinfectant throughout the water tank 001, preventing the growth of microorganisms and algae. This avoids the cumbersome, expensive, and inconvenient water outages associated with traditional manual disinfection methods. The automated disinfection process improves operational convenience and economy while reducing the impact on users' daily water usage. The external disinfection component 100 also reduces the complexity of device installation and maintenance, eliminating the need for the device to be directly attached to the water inlet of the water tank 001 or submerged in the tank, thus expanding its applicability.

[0055] During use, the disinfection component 100 is first installed on the outside of the water tank 001, ensuring that the inlet pipe 200 is connected to the outlet of the water tank 001 and the return pipe 300 is connected to the return end of the water tank 001. The generator 110 of the disinfection component 100 is then activated to supply disinfectant to the storage structure 120. Water from the water tank 001 flows into the storage structure 120 through the inlet pipe 200, mixes with the disinfectant, and then returns to the water tank 001 through the return pipe 300. The disinfectant circulates within the water tank 001 with the water flow, evenly distributing to all water usage points and areas where water flow is stagnant, continuously inhibiting the formation of microorganisms, algae, and biofilms, thereby maintaining water quality standards and preventing secondary pollution. The entire process does not rely on the internal pressure of the water tank 001 and is suitable for various building environments, including underground water tanks and rooftop water tanks 001 in high-rise buildings.

[0056] Specifically, the generator can be an ozone generator. The ozone generator first draws in ambient air and removes moisture, dust, and oil through a built-in air pretreatment system, resulting in dry, clean air. The treated dry air (mainly composed of...) The electrons are fed into a discharge tube device containing two electrodes. When a high-frequency, high-voltage current is applied between the two electrodes, a large amount of blue-violet corona discharge is generated in the gap between them. This discharge is then transmitted through the bombardment of oxygen molecules. This breaks it down into individual, extremely unstable oxygen atoms (O). The highly reactive oxygen atoms (O) rapidly react with the undecomposed oxygen molecules (…). ) combine to form ozone ( Ozone molecules ( Ozone itself possesses powerful oxidizing capabilities, directly attacking the outer structure of microorganisms, causing leaks in the cell membrane and cell wall, altering their permeability, and allowing internal cytoplasm (such as proteins and nucleic acids) to leak out, thus leading to microbial death. It is particularly effective at destroying the protein capsid of viruses, rendering them infectious. Simultaneously, oxygen spontaneously decomposes in water, generating a series of highly oxidizing free radicals. These free radicals attack organic matter in the water, destroying the enzyme systems, genetic material, and cell structure of microorganisms by stealing electrons, achieving a thorough sterilization effect. Ozone's extremely rapid sterilization speed and broad inactivation range make it suitable for disinfection of water in water tanks.

[0057] In some possible implementations, the water inlet pipe 200 is provided with a first connection end 210, and the water inlet pipe 200 is connected to the water tank 001 through the first connection end 210.

[0058] The return water pipe 300 is provided with a second connection end 310. The return water pipe 300 is connected to the water tank 001 through the second connection end 310. The height of the first connection end 210 is lower than the height of the second connection end 310.

[0059] The first connection end 210 serves as the connection interface between the water inlet pipe 200 and the water tank 001. It is located at a lower position in the water tank 001. This low-position connection design can utilize the natural gravity of the water body to ensure that the water in the bottom area of ​​the water tank 001 can preferentially enter the water inlet pipe 200, which is beneficial for pumping out bottom water containing sediment or a high degree of microbial aggregation.

[0060] The second connection end 310 serves as the connection interface between the return water pipe 300 and the water tank 001. By placing the second connection end 310 at a liquid level higher than the first connection end 210, a stable liquid level difference is formed between the outlet of the return water pipe 300 and the inlet of the inlet water pipe 200.

[0061] The low-position arrangement of the first connection end 210 and the high-position arrangement of the second connection end 310 together form a complete water circulation path, so that the disinfected water can return to the water tank 001 from a higher position and form a top-down flow pattern inside the water tank 001.

[0062] The low-level connection of the first connection end 210 effectively extracts water from the easily polluted area at the bottom of the water tank 001, significantly improving the problem of traditional disinfection devices struggling to handle stagnant water at the bottom. Utilizing the height difference between the first connection end 210 and the second connection end 310 establishes a natural circulation power, reducing dependence on the power unit and improving the reliability of system operation. The high-level return water design of the second connection end 310 allows disinfected water to enter from the top of the water tank 001, forming a three-dimensional circulation flow, effectively eliminating disinfection dead zones at different water depths. By establishing a continuous water circulation mechanism, the growth environment for microorganisms, algae, and biofilms throughout the water tank 001 is effectively suppressed.

[0063] In some possible implementations, at least one of the inlet pipe 200 and the return pipe 300 is provided with a booster pump 400.

[0064] The booster pump 400 is used to drive the water in the water tank 001 to flow along the water inlet pipe 200 to the storage structure 120, and can also drive the water in the return pipe 300 to flow to the water tank 001.

[0065] It is known that the location of the booster pump 400 provides a controllable power source for the entire water circulation system, avoiding the limitations of traditional devices that rely on the natural static pressure of the water tank 001 or the pressure of the inlet pipe.

[0066] When the booster pump 400 is installed in the water inlet pipe 200, it can actively draw water from the water tank 001 and push it to the storage structure 120. It is suitable for treating the water in the sedimentation area at the bottom of the water tank 001, ensuring that the bottom water containing high concentrations of pollutants can be effectively transported to the disinfection component 100 for treatment.

[0067] When the booster pump 400 is installed in the return water pipe 300, it can provide sufficient backflow power for the disinfected water, ensuring that the water, which is fully mixed with disinfectant, can overcome pipe resistance and return smoothly to the water tank 001. This design ensures that the disinfected water has sufficient kinetic energy to form an effective circulation flow within the water tank 001.

[0068] By utilizing the forced circulation capability of the booster pump 400, the uniformity of disinfectant distribution within the water tank 001 is significantly improved, effectively eliminating disinfection dead zones in large-capacity or multi-compartment water tanks 001. The configuration of the booster pump 400 eliminates the need for the disinfection device to rely on the installation location of the water tank 001 or natural liquid level differences, expanding the applicability and installation flexibility of the disinfection device. The forced circulation system established by the booster pump 400 effectively disrupts the conditions for the formation of stagnant water flow areas within the water tank 001, fundamentally inhibiting the growth environment of microorganisms, algae, and biofilms. The stable water flow provided by the booster pump 400 ensures that the disinfection component 100 can operate continuously and efficiently, avoiding fluctuations in disinfection effects caused by unstable water flow.

[0069] In some possible implementations, the booster pump 400 is disposed in the water inlet pipe 200, and the height of the booster pump 400 is higher than the height of the first connection end 210.

[0070] Understandably, the high-level installation of the booster pump 400 creates a rising pipeline layout from the first connection end 210 to the booster pump 400, placing the booster pump 400 within the suction range of the inlet pipe 200. Because the booster pump 400 is positioned higher than the first connection end 210, a water column naturally forms within the inlet pipe 200 before the booster pump 400 starts. The static pressure generated by this water column provides the necessary operating conditions for the booster pump 400, effectively preventing the pump from running dry or experiencing cavitation.

[0071] By installing the booster pump 400 above the first connection end 210, operational failures caused by air resistance in the water inlet pipe are effectively prevented, significantly improving system reliability. The stable suction generated by the booster pump 400, which is positioned high, can effectively extract water from the bottom of the water tank 001, which is prone to sedimentation, thus improving the bottom water circulation effect.

[0072] In some possible implementations, the control terminal of the booster pump 400 is equipped with a frequency converter 410, which can control the flow rate of the booster pump 400.

[0073] It is understood that the frequency converter 410, as a control element, can precisely regulate the operating state of the booster pump 400. By changing the frequency characteristics of the output power supply, the frequency converter 410 can precisely control the motor speed of the booster pump 400. The motor speed is directly proportional to the flow output of the booster pump 400, thereby achieving continuous regulation of the flow of the entire system.

[0074] The frequency converter 410 indirectly controls the diffusion rate and distribution range of the disinfectant in the water tank 001 by adjusting the water flow speed in the inlet pipe 200 and the return pipe 300.

[0075] By precisely controlling the flow rate of the booster pump 400 through the frequency converter 410, the disinfection intensity can be adjusted according to the actual pollution status of the water tank 001, achieving on-demand disinfection. The stepless speed regulation capability provided by the frequency converter 410 enables the disinfection system to adapt to the treatment needs of water tanks 001 of different capacities and different water quality conditions. By adjusting the flow rate of the booster pump 400, the circulation speed of the disinfectant in the water tank 001 can be controlled, effectively eliminating disinfection dead zones in large-capacity water tanks 001.

[0076] During operation, the frequency converter 410 outputs power at a specific frequency to the booster pump 400 according to a preset program, real-time monitoring signals, or manual control. When the concentration of pollutants in the water tank 001 is high, the frequency converter 410 increases the output frequency, causing the booster pump 400 to operate at a higher speed, increasing the flow rate in the inlet pipe 200 and the return pipe 300, and accelerating the circulation and distribution of disinfectant in the water tank 001. When the water quality improves, the frequency converter 410 appropriately reduces the output frequency, allowing the booster pump 400 to maintain a basic circulation flow rate in energy-saving mode. This dynamic adjustment method ensures that the disinfectant fully covers all areas of the water tank 001, including areas where water flow is stagnant, while also avoiding energy waste.

[0077] refer to Figure 2 In some possible implementations, the return water pipe 300 is provided with a venturi structure 500 for allowing water flow from the water tank 001 to pass through.

[0078] The Venturi structure 500 is provided with a constriction neck 510, which is connected to the outlet of the storage structure 120. The constriction neck 510 can be used to introduce disinfectant.

[0079] Understandably, the Venturi structure 500, as a component of the return water pipe 300, can generate pressure changes using fluid dynamics principles. This structure is directly integrated into the return water pipe 300 without altering the original pipe connections. The neck 510 of the Venturi structure 500, through its cross-sectional contraction design, increases the water flow velocity through the Venturi structure 500. According to Bernoulli's principle, this increased velocity leads to a decrease in static pressure in that area, creating a localized negative pressure zone.

[0080] The constriction neck 510 is connected to the outlet of the storage structure 120 through a dedicated channel. Utilizing the negative pressure effect generated by the constriction neck 510, it can automatically draw the disinfectant in the storage structure 120 into the main water flow of the return water pipe 300, and violently impact and mix it with the high-speed water flow in the diffusion section. It integrates disinfectant dosing and mixing capabilities, is highly efficient, and does not require additional hybrid power.

[0081] The high-speed water flow through the constricted neck 510 ensures thorough mixing of the disinfectant and water, guaranteeing uniform distribution of the disinfectant within the water tank 001 and effectively eliminating disinfection dead zones. The non-powered design of the Venturi structure 500 reduces system energy consumption and improves the reliability and economy of the disinfection device. The use of the fluid's own energy for disinfectant dosing avoids potential malfunctions associated with complex mechanical dosing devices.

[0082] During operation, water from water tank 001 flows through return pipe 300 and passes through venturi structure 500. At the constriction 510, the flow velocity increases, creating a negative pressure effect. This negative pressure acts on the outlet of storage structure 120 via connecting pipes, automatically drawing disinfectant into the high-speed water flow at the constriction 510. After the disinfectant is thoroughly mixed with the main water flow in the turbulent mixing section of venturi structure 500, the water carrying the uniformly mixed disinfectant returns to water tank 001 via return pipe 300.

[0083] In some possible implementations, the disinfection device further includes a housing 600 having a receiving cavity for accommodating the disinfection assembly 100.

[0084] Understandably, the housing 600, through its internal cavity, provides an independent installation space for the disinfection component 100. This structural design transfers the disinfection component 100 from inside the water tank 001 to an external dedicated container. The enclosed space formed by the housing 600 isolates the disinfection component 100 from the external environment, such as the humid environment of the water tank 001 and other potential interference factors within the building. As a basic support structure, the housing 600 integrates the various parts of the disinfection component 100, such as the generator 110 and the storage structure 120, within a unified cavity, forming a complete equipment unit.

[0085] The enclosure 600 provides a centralized installation space for the disinfection component 100, significantly improving equipment integration and on-site installation efficiency. The physical isolation provided by the enclosure 600 effectively protects the disinfection component 100 from external environmental corrosion, extending the service life of the device. The structural design of the enclosure 600 allows for centralized maintenance and repair of the disinfection component 100 within the enclosure, avoiding interference with the internal environment of the water tank 001.

[0086] In some possible implementations, the disinfection device also includes a controller 700, the output of which is connected to the control terminal of the generator 110, and the controller 700 is disposed within the receiving cavity.

[0087] It should be noted that the controller 700 can have a built-in storage device that can record user water consumption data for water tank 001 at different times. This data can be analyzed manually or using software to establish a water consumption pattern model. This model can then be used to set the start and stop frequency of the booster pump 400 to achieve energy savings.

[0088] The precise control of the generator 110 by the controller 700 enables on-demand disinfection, avoiding waste of disinfectant and over-disinfection.

[0089] During use, the controller 700 continuously monitors and records the user's water consumption data in water tank 001, establishing a water consumption pattern database through its built-in storage device. Based on the analysis results of water consumption patterns, the controller 700 manually adjusts the start-stop frequency and operating duration of the self-priming pump. For example, during peak water consumption periods, the controller 700 increases the operating frequency of the self-priming pump to ensure disinfection effectiveness; during off-peak water consumption periods, the operating frequency is reduced accordingly.

[0090] This application provides a water system including a water tank 001 and the aforementioned disinfection device.

[0091] In some possible implementations, a mixing device 800 is also included, which can at least be used to mix the water flow and disinfectant inside the water tank 001.

[0092] And / or, it also includes a water level sensor 900, which is disposed inside the water tank 001 and can at least obtain the water level inside the water tank 001.

[0093] It is known that the mixing device 800 is located inside the water tank 001 to promote the physical mixing of the disinfectant with the water in the water tank 001. The mixing device 800 can enhance fluid turbulence through mechanical or hydraulic means, thereby improving the diffusion effect of the disinfectant in the water tank 001.

[0094] A water level sensor 900 is installed inside water tank 001 to monitor changes in the water level in water tank 001 in real time. The water level sensor 900 establishes a signal connection with the disinfection device controller 700. When the water level sensor 900 detects that the water level in water tank 001 is lower than a set threshold, it automatically triggers the disinfection device to reduce or stop working.

[0095] The addition of the mixing device 800 significantly improves the uniformity of disinfectant distribution in the water tank 001, effectively eliminating disinfection dead zones formed by stagnant water flow. The real-time monitoring function of the water level sensor 900 provides a guarantee for the safe operation of the disinfection device, preventing potential risks caused by excessive disinfection under low water level conditions. The water level linkage control mechanism effectively avoids water safety problems caused by abnormal increases in disinfectant concentration, improving the reliability of system operation.

[0096] During operation, water tank 001, acting as a water storage unit, normally receives water from the municipal water network or other water sources. The disinfection device establishes a circulating disinfection loop with water tank 001 through inlet pipe 200 and return pipe 300. When the mixing device 800 is configured, it continuously operates inside water tank 001, promoting thorough mixing of the disinfectant-containing water returning from return pipe 300 with the existing water in water tank 001. Water level sensor 900 monitors the water level changes in water tank 001 in real time and transmits the data to controller 700. When water level sensor 900 detects that the water level in water tank 001 has dropped below the safe threshold, controller 700 immediately adjusts the operating parameters of the disinfection device, reducing the disinfectant output of generator 110 or suspending the operation of booster pump 400 to avoid excessively high disinfectant concentrations under low water flow conditions.

[0097] In some embodiments, the mixing device 800 may be a high-pressure nozzle disposed at the second connection end 310.

[0098] The disinfectant-containing water returning from the return pipe 300 is ejected at high speed through one or more high-pressure nozzles. The high-speed jet creates a low-pressure zone around the suction chamber, thereby entraining and mixing the stagnant water flow in the surrounding area of ​​the water tank 001. The two water streams undergo intense momentum exchange and turbulent diffusion within the mixing pipe, achieving thorough mixing. This mixing device 800 has a simple structure, high reliability, and its energy consumption is derived from the booster pump 400, requiring no additional power.

[0099] In other embodiments, the mixing device 800 may be an agitator impeller, which may be top-mounted (long shaft) or submerged on the sidewall, depending on the depth and size of the water tank 001.

[0100] After the motor of the mixing device 800 starts, it drives the stirring impeller located in the water tank 001 to rotate via the drive shaft. The stirring impeller, through shearing and circulation, breaks up the static stratification of the water, creating a forced circulation flow inside the water tank 001, allowing the high-concentration disinfectant water to mix quickly and evenly with the water throughout the tank. The mixing device 800 has high mixing efficiency and speed, making it particularly suitable for large, deep, or complex water tanks 001.

[0101] refer to Figure 3In some embodiments, the water level sensor 900 includes a float 910 and a sensor switch 920. A fixed track 930 is provided inside the water tank 001, and the float 910 is slidably connected to the fixed track 930. The float 910 can slide up and down in the fixed track 930 by buoyancy due to changes in water level. A magnetic metal 940 is provided at the bottom of the float 910, and the sensor switch 920 is provided at the bottom of the water tank 001 at the projection position of the float 910. A magnet 950 is provided around the sensor switch. When the water level in the water tank 001 drops to near the bottom, the magnetic force of the magnet 950 and the magnetic metal 940 is greater than the buoyancy, attracting the float 910 to the sensor switch 920. The sensor switch 920 receives pressure triggering, controlling the booster pump 400 and the generator 110 to shut down, and the disinfection device stops working, preventing excessive disinfectant in the water tank 001 from causing poisoning to the user.

[0102] Of course, multiple water level sensors 900 can also be installed at different water levels in water tank 010. For example, a sensor switch 920 can be installed at the middle water level of water tank 001. When the sensor switch 920 is triggered at that water level, it can control the booster pump 400 and the generator 110 to reduce their operating frequency. By using water level sensors 900 at different water levels to correspond to different operating frequencies of the booster pump 400 and the generator 110, the disinfectant content in water tank 001 can be adjusted to ensure the safety of users' water use.
