Description

Technical Field

[0001] This invention relates to the field of household drinking water purification and disinfection equipment technology, specifically an integrated dual-mode water tank outlet device that combines filtration and ozone disinfection. Background Technology

[0002] As people's living standards improve, their demands for the quality of household water are increasing. Currently, many families install water purifiers in their kitchen sink areas to meet their drinking water filtration needs. Meanwhile, ozone water, due to its strong oxidizing properties, can effectively kill bacteria and viruses and decompose pesticide residues on the surface of fruits and vegetables, and is gradually being applied in the field of household disinfection and cleaning. The traditional method of ozone water preparation utilizes a high-frequency, high-voltage corona field to induce an electrochemical reaction in oxygen to produce ozone, which is then injected into water to form ozone water. Currently, the use of water electrolysis to generate ozone is becoming increasingly widespread. This involves using water electrolysis ozone generators, such as the one disclosed in CN223188987U, and the ozone reversing circuit and ozone generator disclosed in CN222861664U. An electrolytic water ozone generator typically consists of a membrane electrode assembly, current collector and conductor components, electrode plates, a housing, a power supply, and a controller. The ozone generated by the electrolytic water ozone generator dissolves in water to form functional water. The ozone produced is of high purity, and the ozone concentration can be adjusted through the controller to obtain ozone water of appropriate concentration when the water is discharged.

[0003] In existing technologies, water purifiers and ozone disinfection devices are usually two separate products. Water purifiers are generally installed in a cabinet under the sink, with water dispensed through a separate faucet; while ozone disinfection devices either use a handheld disinfection gun or require a complex external device attached to the faucet. This separate design not only takes up space in the sink area but is also cumbersome to operate, requiring users to draw water from two different outlets.

[0004] On the other hand, most kitchen sinks on the market today have multiple holes on the countertop, including holes for hot and cold water faucets and usually a hole for a push-button detergent dispenser. As push-button detergent dispensers are gradually being replaced by wall-mounted or sensor-operated dispensers, this hole is often left unused and not effectively utilized.

[0005] Therefore, how to utilize the unused detergent outlets on the sink countertop to design a highly integrated, easy-to-install water outlet device that can flexibly switch between water filtration and ozone disinfection modes has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] In view of the above-mentioned deficiencies of the prior art, the purpose of the present invention is to provide an integrated dual-mode water tank outlet device that combines filtration and ozone disinfection.

[0007] The technical solution of this invention is: an integrated dual-mode water tank outlet device for filtration and ozone disinfection, comprising a base, an inner sleeve fixed inside the base, an ozone generator fixed inside the inner sleeve, an outer shell fixedly connected to the top of the inner sleeve, a filter element placed inside the outer shell, a protective cover covering the outer shell, a threaded sleeve extending vertically fixed at the lower end of the base, an inlet pipe and an outlet pipe extending vertically through the threaded sleeve, the inlet pipe communicating with the inside of the inner sleeve, the inside of the inner sleeve communicating with the inside of the outer shell, the ozone generator having an ozone generating chamber inside, the outlet at the lower end of the filter element communicating with the ozone generating chamber, and the ozone generating chamber communicating with the outlet pipe.

[0008] Furthermore, the inner sleeve has a water inlet chamber, the outer sleeve has a filter chamber, the lower end of the water inlet chamber is connected to the upper end of the water inlet pipe, and the upper end of the water inlet chamber is connected to the lower end of the filter chamber.

[0009] Furthermore, the upper end of the ozone generator is fixed with a plug-in part, the center of which has a guide hole that communicates with the ozone generating chamber. The lower end of the filter element is plugged into the plug-in part, and the water outlet at the lower end of the filter element is connected to the guide hole.

[0010] Furthermore, the bottom of the ozone generating chamber has an ozone water outlet that is connected to the upper end of the water outlet pipe.

[0011] Furthermore, a controller is installed inside the base, and a control switch is installed on the outside of the base.

[0012] Furthermore, the threaded sleeve passes through the washing liquid hole in the water tank.

[0013] Furthermore, the ozone generator uses semiconductor electrodes to electrolyze water under applied voltage to produce ozone.

[0014] Furthermore, the semiconductor electrode is a metal-based BDD electrode. Metal-based BDD electrodes have extremely low resistance, which helps reduce the overall electrode impedance; they are more resistant to shock and mechanical wear, making them suitable for complex and dynamic working environments; the passivation layer of the metal-based BDD electrode is stable, allowing it to maintain a low background current for extended periods; and they have a wide operating current range, enabling long-term, highly efficient electro-oxidation reactions (generating hydroxyl radicals and ozone).

[0015] The integrated filtration and ozone disinfection dual-mode sink water outlet device provided by this invention has the following advantages: it can be directly installed in the original washing liquid hole of the sink, and achieves the integration of dual functions of water filtration and ozone disinfection without changing the original hot and cold water faucet layout.

Detailed Implementation

[0021] To provide a more intuitive and complete understanding of the technical solution of this invention, the following non-limiting features are described in conjunction with the accompanying drawings:

[0022] like Figure 1 — Figure 4 As shown, the integrated dual-mode water tank outlet device for filtration and ozone disinfection includes a base 1, an inner sleeve 2 fixed inside the base 1, an ozone generator 3 fixed inside the inner sleeve 2, an outer shell 4 fixedly connected to the top of the inner sleeve 2, a filter element 5 inside the outer shell 4, and a protective cover 6 covering the outer shell 4. A threaded sleeve 7 extending vertically is fixed to the lower end of the base 1. An inlet pipe 8 and an outlet pipe 9 both extend vertically through the threaded sleeve 7. The inlet pipe 8 is connected to the inside of the inner sleeve 2, and the inside of the inner sleeve 2 is connected to the inside of the outer shell 4. The ozone generator 3 has an ozone generating chamber 31 inside. The outlet of the filter element 5 at the lower end is connected to the ozone generating chamber 31, and the ozone generating chamber 31 is connected to the outlet pipe 9.

[0023] like Figure 2 , Figure 4 As shown, the inner sleeve 2 has a water inlet chamber 21, and the outer sleeve 4 has a filter chamber 41. The lower end of the water inlet chamber 21 is connected to the upper end of the water inlet pipe 8, and the upper end of the water inlet chamber 21 is connected to the lower end of the filter chamber 41.

[0024] like Figure 2 As shown, in order to facilitate the installation of filter element 5, an insertion part 10 is fixed at the upper end of ozone generator 3. The insertion part 10 has a guide hole 101 in the center that communicates with ozone generating chamber 31. The lower end of filter element 5 is inserted into insertion part 10, and the water outlet at the lower end of filter element 5 is connected to guide hole 101.

[0025] like Figure 2 As shown, the bottom of the ozone generating chamber 31 has an ozone water outlet 32 ​​that is connected to the upper end of the water outlet pipe 9.

[0026] like Figure 1 , Figure 3As shown, a controller 11 is installed inside the base 1, and a control switch 12 is installed on the outside of the base 1. The ozone generator 3 uses semiconductor electrodes to electrolyze water to produce ozone under applied voltage. A typical electrode reaction is as follows:

[0027] anode: ;

[0028] cathode: .

[0029] The semiconductor electrode is a metal-based BDD electrode (boron-doped diamond electrode). Metal-based BDD electrodes have extremely low resistance, which helps reduce the overall electrode impedance; they are more resistant to shock and mechanical wear, making them suitable for complex and dynamic working environments; the passivation layer of the metal-based BDD electrode is stable, maintaining a low background current for extended periods; and they have a wide operating current range, enabling long-term, highly efficient electro-oxidation reactions (generating hydroxyl radicals and ozone).

[0030] Compared to traditional electrolytic methods for ozone production, which generate ozone through an oxidation reaction at the anodic interface by electrolyzing pure water or acidic solutions, this method is limited by high equipment costs and energy consumption. This application effectively solves these problems, offering advantages such as small size, low energy consumption, and high concentration and purity of generated ozone.

[0031] During installation, threaded sleeve 7 is passed through the detergent drain hole in the sink, and then the threaded sleeve 7 is secured to the sink with a nut. Water outlet pipe 9 is connected to the faucet.

[0032] During operation, raw water enters through the inlet pipe 8, flows through the inlet chamber 21 and the filter chamber 41 into the filter element 5. After being purified by the filter element 5, the water enters the ozone generation chamber 31, where the ozone generator 3 operates to produce ozone water. The ozone water flows out through the outlet pipe 9 and onto the faucet. When ozone water is no longer needed, the device can be turned off to obtain purified water.

[0033] The integrated filtration and ozone disinfection dual-mode sink water outlet device provided by this invention can be directly installed in the original washing liquid hole of the sink, realizing the dual functions of water filtration and ozone disinfection without changing the original hot and cold water faucet layout.

[0034] Of course, the above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention.
