[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0023] like Figure 1 , 4 As shown, in the first embodiment of the electrolytic water sterilization and disinfection device of the present invention, the disinfection device 10 includes a hollow tube 11, a first end cap 12 covering the first end of the tube 11, a second end cap 13 covering the second end of the tube 11, a first pipe connector 14 disposed on the first end cap 12 and communicating with the tube 11, a second pipe connector 15 disposed on the second end cap 13 and communicating with the tube 11, N anode plates 16 arranged in parallel inside the tube 11, and N+1 cathode plates 17 disposed inside the tube 11 and interleaved with the N anode plates 16. The first end cap 12 is provided with an anode column 18 passing through the first end cap 12 and electrically connected to all N anode plates 16, and a cathode column 19 passing through the first end cap 12 and electrically connected to all N+1 cathode plates 17, wherein N is a positive integer greater than or equal to 2.

[0024] When using the electrolyzed water sterilization and disinfection device 10 of the present invention, the first pipe connector 14 is connected to the water inlet pipe, and the second pipe connector 15 is connected to the water outlet pipe. Water flows into the pipe body 11 through the first pipe connector 14. The control power supply controls the anode column 18 and cathode column 19 to be energized, and the N anode plates 16 and N+1 cathode plates 17 are energized, causing the disinfection device 10 to electrolyze water and generate hypochlorous acid, hydroxyl radicals, and ozone microbubbles in the water. The generated ozone microbubbles mix with the water during the drifting process to generate ozone water, thereby achieving sterilization and disinfection.

[0025] Furthermore, a flow signal sensor can be installed inside the first end cap 12. When the flow signal sensor detects water flow inside the pipe body 11, the control power supply is energized to the anode column 18 and the cathode column 19.

[0026] Specifically, such as Figure 1 As shown, the first end of the N anode plates 16 is provided with a first fixing plate 20 that is fixedly connected to the N anode plates 16. The first fixing plate 20 is vertically fixedly connected to each of the N anode plates 16. The anode column 18 is vertically fixedly connected to the first fixing plate 20.

[0027] Similarly, the first end of the N+1 cathode plates 17 is provided with a second fixing plate 21 that is fixedly connected to the N+1 cathode plates 17. The second fixing plate 21 is vertically fixedly connected to each of the N+1 cathode plates 17, and the cathode column 19 is vertically fixedly connected to the second fixing plate 21.

[0028] Furthermore, the second ends of the N anode plates 16 and the second ends of the N+1 cathode plates 17 are provided with isolation plates 22 for fixing the N anode plates 16 and the N+1 cathode plates 17.

[0029] To facilitate water flow, the first fixing plate 20, the second fixing plate 21 and the isolation plate 22 are all provided with water passage holes for water to pass through; and / or, the first fixing plate 20, the second fixing plate 21 and the isolation plate 22 are provided with water flow holes between them and the pipe body 11 for water to pass through.

[0030] To achieve better disinfection and sterilization effects, in the second embodiment of this application, such as Figure 2 , 3 As shown, a filter assembly 23 is provided inside the tube body 11 at one end near the second end cap 13.

[0031] Specifically, the filter assembly 23 includes a housing 24, an inlet 25 disposed at a first end of the housing 24, an outlet 26 disposed at a second end of the housing 24, a filter screen 27 disposed inside the housing 24 near the inlet 25, and an activated carbon pack 28 disposed inside the housing 24 near the outlet 26.

[0032] When the water flows through the filter screen 27, particulate impurities are filtered out. When the water flows through the activated carbon pack 28, toxic and harmful substances in the water are adsorbed.

[0033] Preferably, the filter screen 27 is a metal filter screen 27, and the filter screen 27 is a conical or bowl-shaped filter screen 27, which gradually protrudes from the edge to the center toward the first end of the tube body 11.

[0034] By setting a conical or bowl-shaped filter screen 27, impurities can be prevented from accumulating in the middle of the filter screen 27 when water flows through it. Because the filter screen 27 is conical or bowl-shaped with a convex center, the impurities attached to the middle of the filter screen 27 can be pushed towards the filter screen 27 for easy access under the impact of the water flow, thus reducing the impact of impurities on the water flow.

[0035] Furthermore, the first end of the outer casing 24 is provided with a funnel-shaped third end cap 29. The large-diameter end of the third end cap 29 is fixedly connected to the first end of the outer casing 24. The large-diameter end of the third end cap 29 is close to the second end cap 13, and the small-diameter end of the third end cap 29 is close to the first end cap 12. The small-diameter end of the third end cap 29 forms the water inlet 25.

[0036] Preferably, the inner wall of the third end cap 29 is provided with a plurality of protrusions 30 protruding from the inner wall surface of the third end cap 29.

[0037] When impurities are pushed toward the edge of the filter screen 27, they can be hooked or blocked by the protrusions 30 on the inner wall of the third end cap 29, preventing the impurities from continuing to move in the pipe body 11 and improving the smoothness of the water flow.

[0038] It is worth mentioning that the sterilization and disinfection device in this embodiment of the invention can be an intelligent control power supply. A flow sensor can be installed at the water inlet of the sterilization and disinfection device, such as the first pipe connector 14. The flow sensor is electrically connected to the intelligent control power supply and can provide a water flow signal to the intelligent control power supply, enabling the intelligent control power supply to obtain the water flow rate through the sterilization and disinfection device in real time. The intelligent control power supply can control the electrolysis current based on the water flow rate or operate according to a set time, thereby meeting the requirements for different disinfectant concentrations.

[0039] Compared with the prior art, when using the electrolyzed water sterilization and disinfection device of the present invention, the first pipe connector is connected to the inlet pipe and the second pipe connector is connected to the outlet pipe. Water flows into the pipe body through the first pipe connector. The power supply controls the anode column and cathode column to be energized. N anode plates and N+1 cathode plates are energized, and the disinfection device electrolyzes water to generate hypochlorous acid, hydroxyl radicals and ozone microbubbles in the water. The generated ozone microbubbles mix with water during the drifting process to generate ozone water, thereby achieving sterilization and disinfection.

[0040] Furthermore, in this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
