Description

Technical Field

[0001] This utility model relates to the field of ozone generating equipment technology, and in particular to an active oxygen generating device with a long service life. Background Technology

[0002] Ozone water has strong oxidizing properties and can effectively eliminate harmful bacteria remaining in water. Since ozone produces oxygen or water after reduction, it is a harmless and highly efficient oxidizing medium for the human body and can perfectly replace currently used chemical reagents such as hypochlorous acid for the disinfection of drinking water or other medical equipment.

[0003] Currently, diamond-based BDD materials are being gradually applied to ozone production, bringing ozone water into the public eye. However, producing ozone water requires not only BDD (boron-doped diamond) as an electrode, but also a suitable proton exchange membrane to improve ozone production efficiency.

[0004] Currently, the most common method for preparing ozone water is the water-passing method, which involves designing a water-passing device that integrates BDD, proton exchange membrane, power supply electrodes, etc. This method can achieve an ozone concentration of 1 mg / L in water. However, since such devices are mainly used in household and other fields, the water quality is hard water. Calcium and magnesium ions in hard water easily form calcium and magnesium compounds after passing through such devices and adhere to the cathode, affecting the normal use of the device. This results in a short service life for such water-passing devices, which is not conducive to large-scale application.

[0005] Therefore, it is necessary to provide an active oxygen generator with a long service life to solve the above-mentioned technical problems. Utility Model Content

[0006] This invention provides a long-life active oxygen generator, which solves the problem of short lifespan and low ozone generation efficiency in existing water-type ozone generators due to calcium and magnesium ions forming scale on the electrode surface in hard water.

[0007] To solve the above-mentioned technical problems, this utility model provides a long-life activated oxygen generator, comprising:

[0008] The lower housing has an upper housing on its top.

[0009] An impeller cover is disposed on the inner side of the lower shell and the upper shell. An impeller is fixedly installed at the bottom of the impeller cover. A cleaning brush is disposed on one side of the impeller. A second screw is disposed inside the cleaning brush. One end of the second screw is threadedly connected to the impeller. An anode conductive plate, a BDD, a proton exchange membrane, a gasket, and a cathode conductive plate are disposed sequentially from top to bottom between the impeller cover and the impeller. The side of the cleaning brush is respectively attached to the side of the anode conductive plate, the BDD, the proton exchange membrane, and the cathode conductive plate.

[0010] Preferably, a sealing ring is provided between the upper housing and the lower housing.

[0011] Preferably, both the anode conductive sheet and the cathode conductive sheet are provided with optical axis bolts inside, and the outer surfaces of the two optical axis bolts are provided with rubber plugs. The two rubber plugs are respectively fixedly installed at the bottom of the lower housing and the top of the upper housing.

[0012] Preferably, the outer surfaces of both optical axis bolts are threaded with a first nut, one of which is located at the top of the upper housing and the other at the bottom of the lower housing.

[0013] Preferably, bolts are provided inside the anode conductive sheet, the BDD, the proton exchange membrane, the gasket, and the cathode conductive sheet, and a second nut is threaded onto the outer side of the bolt, with the second nut located on the top of the anode conductive sheet.

[0014] Preferably, a connecting pipe is fixedly installed at the output end of the lower housing, a filter frame is fixedly installed at the output end of the connecting pipe, a filter plate is fixedly installed on the inner side of the filter frame, a threaded ring is fixedly installed at the bottom of the filter frame, and a storage pipe is threadedly connected to the inner side of the threaded ring.

[0016] Compared with related technologies, the active oxygen generator with a long service life provided by this utility model has the following beneficial effects:

[0017] This invention provides a long-life active oxygen generator. Through the cooperation of structures such as impeller and cleaning brush, when in use, the water flow drives the impeller to rotate, which in turn drives the cleaning brush fixed on the impeller to clean the area between the two conductive plates that is prone to scale buildup.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] First Embodiment

[0028] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a long-life active oxygen generator provided by this utility model; Figure 2 for Figure 1 The diagram shows another perspective of the structure. Figure 3 for Figure 1 The diagram shows the structure of the impeller and impeller cover. Figure 4 for Figure 1 The diagram shows the structure of the cleaning brush. Figure 5 for Figure 1 The diagram shows an explosion structure. A long-life activated oxygen generator includes: a lower housing 1, with an upper housing 2 disposed on top of the lower housing 1;

[0029] An impeller cover 4 is disposed on the inner side of the lower shell 1 and the upper shell 2. An impeller 41 is fixedly installed at the bottom of the impeller cover 4. A cleaning brush 42 is disposed on one side of the impeller 41. A second screw 43 is disposed inside the cleaning brush 42. One end of the second screw 43 is threadedly connected to the impeller 41. An anode conductive sheet 5, a BDD 6, a proton exchange membrane 7, a gasket 15, and a cathode conductive sheet 8 are disposed sequentially from top to bottom between the impeller cover 4 and the impeller 41. The side of the cleaning brush 42 is respectively attached to the side of the anode conductive sheet 5, the BDD 6, the proton exchange membrane 7, and the cathode conductive sheet 8.

[0030] A sealing ring 14 is provided between the upper housing 2 and the lower housing 1.

[0031] Both the anode conductive sheet 5 and the cathode conductive sheet 8 are provided with optical axis bolts 9 inside, and both optical axis bolts 9 are provided with rubber plugs 11 on their outer sides. The two rubber plugs 11 are respectively fixedly installed at the bottom of the lower housing 1 and the top of the upper housing 2.

[0032] Both of the optical axis bolts 9 have a first nut 10 threadedly connected to their outer surfaces. One first nut 10 is located on the top of the upper housing 2, and the other first nut 10 is located on the bottom of the lower housing 1.

[0033] Bolts 12 are provided inside the anode conductive sheet 5, the BDD 6, the proton exchange membrane 7, the gasket 15 and the cathode conductive sheet 8. A second nut 13 is threaded onto the outer side of the bolt 12 and is located on the top of the anode conductive sheet 5.

[0034] By placing an impeller 41 in the cavity, the impeller 41 is driven to rotate by the power of water, which in turn causes the cleaning brush 42 mounted on the impeller 41 to rotate and clean the electrode.

[0035] The BDD6 uses circular electrode plates, which facilitates production and saves costs. A gasket 15 is added between the anode conductive plate 5 and the proton exchange membrane 7, which allows the generated oxygen water to be discharged in time, avoiding the accumulation of oxygen water that accelerates the corrosion of the proton exchange membrane 7 and increasing the service life of the proton exchange membrane 7.

[0036] The working principle of the long-life active oxygen generator provided by this utility model is as follows:

[0037] During use, external water flows into the internal cavity of the lower housing 1 from the water inlet. The water flow impacts the blades of the impeller 41, generating a driving torque that causes the impeller 41 to rotate around its central axis. Since the cleaning brush 42 is fixed to the side of the impeller 41 by the second screw 43, it will rotate synchronously with the impeller.

[0038] The rotating cleaning brush 42 is always in contact with the surfaces of the anode conductive sheet 5, BDD6 (boron-doped diamond), proton exchange membrane 7 and cathode conductive sheet 8. Through mechanical friction, it continuously removes the calcium and magnesium compound scale (calcium and magnesium ions in hard water are prone to precipitate during electrolysis) adhering to the surfaces of these components.

[0039] Meanwhile, the anode conductive plate 5 and the cathode conductive plate 8 are connected to an external power source to form an electrolysis circuit. Under the separation effect of the proton exchange membrane 7, an oxidation reaction occurs in the anode region to generate ozone, while a reduction reaction occurs in the cathode region. Because the scale is cleaned in time, the surface of the conductive plate remains clean, the ion exchange efficiency is improved, and the ozone generation reaction is more complete, thereby increasing the concentration of active oxygen (ozone).

[0040] The sealing ring 14 ensures the sealing between the upper housing 2 and the lower housing 1 to prevent water leakage; the optical axis bolt 9, together with the first nut 10 and the rubber plug 11, realizes the insulation, fixation and sealing of the conductive sheet and the housing; the bolt 12 and the second nut 13 fix the anode conductive sheet 5, BDD6, proton membrane 7, gasket 15 and cathode conductive sheet 8 into a whole component, ensuring the stable fit of each layer structure and maintaining the stability of the electrolysis reaction.

[0041] Compared with related technologies, the active oxygen generator with a long service life provided by this utility model has the following beneficial effects:

[0042] The impeller 41 and cleaning brush 42 work together to achieve the following: during use, the water flow drives the impeller 41 to rotate, which in turn drives the cleaning brush 42 fixed on the impeller 41 to clean the area between the two conductive plates that is prone to scale buildup. This reduces the risk of scale buildup in the main reaction chamber, while also improving ion exchange, increasing reaction efficiency, enhancing active oxygen concentration, and significantly extending the product's service life, which is beneficial for large-scale applications.

[0043] Second Embodiment

[0044] Please refer to the following: Figure 6 and Figure 7 Based on the first embodiment of this application which provides a long-life activated oxygen generator, the second embodiment of this application proposes another long-life activated oxygen generator. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0045] Specifically, the second embodiment of this application provides a high-life-cycle active oxygen generator, wherein a connecting pipe 16 is fixedly installed at the output end of the lower housing 1, a filter frame 17 is fixedly installed at the output end of the connecting pipe 16, a filter plate 20 is fixedly installed on the inner side of the filter frame 17, a threaded ring 18 is fixedly installed at the bottom of the filter frame 17, and a storage tube 19 is threadedly connected to the inner side of the threaded ring 18.

[0046] The filter plate 20 is set in an inclined state.

[0047] When scale needs to be cleaned, the user can rotate the storage tube 19 to unscrew it from the inner side of the threaded ring 18, and then clean the impurities on the inner side of the storage tube 19.

[0048] The working principle of the long-life active oxygen generator provided by this utility model is as follows:

[0049] When in use, water flows into the interior of the connecting pipe 16 through the output end of the lower housing 1, then enters the inner side of the filter frame 17, and is then filtered by the filter plate 20, causing scale to enter the inner side of the storage pipe 19 for storage. The filtered water is then discharged through the side of the filter frame 17.

[0050] Compared with related technologies, the active oxygen generator with a long service life provided by this utility model has the following beneficial effects:

[0051] The connecting pipe 16, filter frame 17, threaded ring 18, storage pipe 19 and filter plate 20 work together to filter the water discharged from the lower housing 1 during use, preventing the scale removed from cleaning from entering the subsequent pipes.
