Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, specifically a pure water equipment with pure water preparation and pipeline self-cleaning and disinfection functions. Background Technology

[0002] A water purifier is a water purification device that uses multi-stage filters to purify water. The treatment primarily employs physical methods such as filtration, adsorption, and reverse osmosis without adding chemicals. Dental hospitals, clinics, and other medical institutions use water purifiers to produce pure water for medical purposes. The pure water supply pipes of these machines need to be disinfected periodically. Currently, the disinfection method involves disassembling the pure water supply pipes, manually disinfecting them with disinfectant, and then rinsing them with pure water, which is very inconvenient. Furthermore, existing water purifiers store pre-prepared pure water in the tank after production. Because this water is stored in the tank for extended periods, it is prone to microbial growth and bacterial proliferation, potentially leading to excessive levels of microorganisms or bacteria, thus resulting in pure water that does not meet the requirements of dental hospitals and clinics.

[0018] like Figures 1 to 4 As shown, a preferred embodiment of this utility model provides a pure water equipment with pure water preparation and pipeline self-cleaning and disinfection functions. It includes a pure water preparation device, a hypochlorous acid disinfectant water preparation device, a microbial detection module 3, a disinfection device, and a controller 5. The hypochlorous acid disinfectant water preparation device and the pure water preparation device are connected in parallel. The inlet ends of both devices are connected to an inlet pipe 6, and their outlet ends are connected to a supply pipe 7. The pure water preparation device includes a pre-filter 11, a booster pump 12, a reverse osmosis filter 13, a first water tank 14, and a pump connected sequentially via pipelines. Pump 15; The hypochlorous acid disinfection water preparation device includes a hypochlorous acid generator 21, a second water tank 22, and a liquid pump 23 connected in sequence by pipelines; The disinfection device includes a return water pipeline 41 and a disinfector 42 installed in the first water tank 14.

The microbial detection module 3 is used to detect the density of microorganisms in the water in the first water tank 14. The controller 5 controls the disinfector 42 to disinfect the water. The return water pipeline 41 connects the first water tank 14 and the booster pump 12.

[0019] The pre-filter 11 is used for preliminary filtration of water. The booster pump 12 is used to force water under certain pressure through the reverse osmosis filter 13, which is used to filter the water to produce pure water. The reverse osmosis filter 13 is provided with an inlet 131 and a pure water outlet 132. The first water tank 14 is used to store the pure water prepared by the reverse osmosis filter 13. Users can directly take water from the first water tank 14, which can reduce the waiting time for users to prepare pure water. The first water tank 14 is provided with an inlet 141, a first outlet 142, and a second outlet 143. The water pump 15 is used to directly extract the pure water in the first water tank 14 for users to collect.

[0020] The inlet pipe 6 can be connected to municipal water pipes or other water sources, and the supply pipe 7 is connected to the outlet device, which can be a mechanical faucet or an electric faucet. Specifically, the inlet pipe 6 is connected to the inlet of the pre-filter 11 through a pipeline, the outlet of the pre-filter 11 is connected to the inlet of the booster pump 12 through a pipeline, the outlet of the booster pump 12 is connected to the inlet 131 of the reverse osmosis filter 13 through a pipeline, the pure water outlet 132 of the reverse osmosis filter 13 is connected to the inlet 141 of the first water tank 14 through one pipeline, the pure water outlet 132 of the reverse osmosis filter 13 is connected to the supply pipe 7 through another pipeline, the first outlet 142 of the first water tank 14 is connected to the inlet of the water pump 15 through a pipeline, and the outlet of the water pump 15 is connected to the supply pipe 7 through a pipeline.

[0021] A first solenoid valve 16 is installed on the pipeline between the inlet of the pre-filter 11 and the inlet pipe 6, the pipeline between the pure water outlet 132 of the reverse osmosis filter 13 and the supply pipe 7, and the pipeline between the outlet of the water pump 15 and the supply pipe 7.

[0022] The hypochlorous acid generator 21 is used to produce hypochlorous acid disinfectant water, the second water tank 22 is used to store the hypochlorous acid disinfectant water, and the pump 23 is used to extract the hypochlorous acid disinfectant water from the second water tank 22 for user disinfection. The hypochlorous acid generator 21 and the pump 23 are electrically connected to the controller 5. The controller 5 controls the hypochlorous acid generator 21 to produce hypochlorous acid disinfectant water and controls the pump 23 to extract the hypochlorous acid disinfectant water from the second water tank 22 for user disinfection.

[0023] Preferably, the second water tank 22 is equipped with an upper liquid level sensor 221 and a lower liquid level sensor 222 for detecting the water level. The upper liquid level sensor 221 and the lower liquid level sensor 222 are electrically connected to the controller 5, and the upper liquid level sensor 221 and the lower liquid level sensor 222 send the detected liquid level signal to the controller 5.

[0024] Specifically, the water inlet of the hypochlorous acid generator 21 is connected to the water inlet pipe 6 through a pipeline, the disinfectant outlet of the hypochlorous acid generator 21 is connected to the liquid inlet of the second water tank 22 through a pipeline, the liquid outlet of the second water tank 22 is connected to the liquid inlet of the pump 23 through a pipeline, and the liquid outlet of the pump 23 is connected to the water supply pipe 7 through a pipeline.

[0025] A second solenoid valve 24 is installed on the pipeline between the water inlet of the hypochlorous acid generator 21 and the inlet pipe 6, and on the pipeline between the outlet of the pump 23 and the supply pipe 7. The second solenoid valve 24 is used to control the on / off state of the hypochlorous acid disinfectant preparation device. The first solenoid valve 16 and the second solenoid valve 24 are electrically connected to the controller 5, and the controller 5 controls the opening and closing of the first solenoid valve 16 and the second solenoid valve 24.

[0026] The microbial detection module 3 detects the density of microorganisms in the water in the first water tank 14 and generates a corresponding detection signal for the controller 5. The detection signal indicates the density of microorganisms in the water in the first water tank 14. The sterilizer 42 is used to disinfect the water in the first water tank 14 when the density of microorganisms in the first water tank 14 indicated by the detection signal exceeds the density threshold, thereby improving the water quality of the water supply pipe 7. The sterilizer 42 can be an ozone generator, an ultraviolet disinfection lamp, etc.

[0027] One end of the return water pipe 41 is connected to the second outlet 143 of the first water tank 14, and the other end is connected to the inlet of the booster pump 12. A return water solenoid valve 411, which is electrically connected to the controller 5, is installed on the return water pipe 41. The return water solenoid valve 411 is activated when the microbial density in the first water tank 14, as indicated by the detection signal, exceeds the density threshold. After the return water solenoid valve 411 is activated, water can circulate between the booster pump 12, the reverse osmosis filter element 13, and the first water tank 14. The circulation of water can ensure that the water is thoroughly disinfected. In addition, impurities generated during the disinfection process of the sterilizer 42 can be filtered by the reverse osmosis filter element 13, further improving the quality of the water output from the water supply pipe 7.

[0028] The controller 5 can be constructed using electronic components such as timers, comparators, registers, and digital logic circuits, or implemented using processor chips such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits.

[0029] In use, under the control of the controller 5, the first solenoid valve 16 and the second solenoid valve 24 at the inlet of the hypochlorous acid disinfectant preparation device and the pure water preparation device are opened. Tap water flows through the inlet pipe 6 to the hypochlorous acid disinfectant preparation device, which then begins to prepare disinfectant. The prepared disinfectant flows into the second water tank 22. When the liquid level in the second water tank 22 reaches the upper liquid level sensor 221, the upper liquid level sensor 221 sends the detected liquid level signal to the controller 5. The controller 5 then issues a command to close the second solenoid valve 24 at the inlet of the hypochlorous acid disinfectant preparation device and controls the hypochlorous acid generator 21 to stop preparing disinfectant. The disinfectant is then stored in the second water tank 22 for later use. Another stream of tap water flows to the pure water preparation device. Controller 5 controls the start of booster pump 12, which forces water at a certain pressure through reverse osmosis filter 13. Reverse osmosis filter 13 then produces pure water into the first water tank 14. The prepared pure water enters the first water tank 14. If pure water needs to be output externally, controller 5 controls the start of water pump 15 and opens the first solenoid valve 16 at the outlet of the pure water preparation device. Water pump 15 draws water from the first water tank 14 into the water supply pipe 7. If disinfectant is needed to disinfect the water supply pipe 7, controller 5 first closes the first solenoid valves 16 at both ends of the pure water preparation device, then opens the liquid pump 23 and the second solenoid valve 24 at the outlet of the hypochlorous acid disinfectant preparation device. Under the action of liquid pump 23, hypochlorous acid disinfectant is output into the water supply pipe 7 for disinfection. After disinfection, the system switches to pure water output mode to rinse away any remaining disinfectant. When the level of hypochlorous acid disinfectant water in the second water tank 22 is lower than that of the lower level sensor 222, the lower level sensor 222 sends the detected level signal to the controller 5. The controller 5 controls the hypochlorous acid generator 21 to prepare hypochlorous acid disinfectant water. The microbial detection module 3 detects the density of microorganisms in the water in the first water tank 14 to generate a corresponding detection signal to the controller 5. The controller 5 controls the sterilizer 42 to disinfect the water. The return water solenoid valve 411 is activated when it detects that the microbial density in the first water tank 14 exceeds the density threshold. After the return water solenoid valve 411 is activated, the water circulates between the booster pump 12, the reverse osmosis filter 13 and the first water tank 14, and the water is fully disinfected through the circulation of water.

[0030] The pure water equipment of this invention, which includes pure water preparation and self-cleaning and disinfection functions for the water supply pipe 7, has the functions of pure water preparation, disinfectant preparation, and automatic cleaning and disinfection of the water supply pipe 7. When disinfection is required, this pure water equipment can first disinfect with disinfectant and then clean with pure water, thereby replacing manual disinfection and cleaning of the water supply pipe 7, saving time and effort, and making it more convenient. In addition, the above-mentioned pure water equipment can detect the water quality of the produced pure water through the microbial detection module 3, and purify the pure water through the sterilizer 42 to ensure that the produced pure water meets the usage requirements.
