Description

Technical Field

[0001] This utility model relates to the field of water purification equipment, and in particular to a silver ion generating device. Background Technology

[0002] Using silver ions in water purifiers is a widely used water purification technology. It has many advantages, including sterilization, odor removal, water desalination, and improved taste, and is very safe and reliable. By introducing silver ions into the water purifier, its bactericidal and disinfecting properties are utilized to achieve water purification. It has excellent antibacterial properties and can kill common bacteria, viruses, fungi, and other microorganisms.

[0003] There are currently many silver ion generating devices on the market. One type is a water purifier with its own power generation function. It uses the water flow from the water supply pipe to drive a motor to generate electricity, which in turn powers the silver plates, causing the silver ions to dissolve into the water.

[0004] The existing products have the following shortcomings: I. Most current hydroelectric power generation uses alternating current (AC), which needs to be converted to direct current (DC) to achieve stable electrolysis of silver ions. Energy loss occurs during this conversion process, reducing the output voltage. Existing hydroelectric power generation modules can only provide a fixed output. When the water pressure in the supply pipe is low, the output voltage is low, the efficiency of silver electrolysis is low, and the silver ion concentration is insufficient, failing to achieve the expected sterilization effect. Similarly, when the conductivity of the water is low, the efficiency of silver electrolysis is also low, resulting in insufficient silver ion concentration. II. During silver ion electrolysis in aqueous solutions, the silver sheet undergoes an oxygen evolution reaction, reducing silver ion production. Under high current density, silver ions at the anode easily form a black passivation layer (Ag₂O / AgO) on the surface of the silver sheet, which also hinders silver ion production. Summary of the Invention

[0005] In view of this, it is necessary to provide a silver ion generating device that can adapt to a stable power supply and a uniform silver ion concentration in aqueous solution.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a silver ion generating device, comprising: The pipe is a one-piece molded pipe, and a first installation channel and a second installation channel are sequentially provided on the side wall of the pipe along the direction of water flow. A silver ion generator is detachably and fixedly connected to the first mounting channel. The silver ion generator includes a socket, an anode, and a cathode. The socket has conductive contacts that are electrically connected to the anode and cathode respectively. The anode is a silver sheet or a magnesium sheet, and the cathode is a silver sheet or graphite. A DC generator is fixedly connected within the second mounting channel. The DC generator includes a worm gear with blades whose spacing can be adjusted according to different inlet water pressures. The DC generator provides power to the silver ion generator. A sensing unit is electrically connected to the DC generator; the sensing unit includes a water pressure sensor and a conductivity sensor, the water pressure sensor being located at the inlet of the worm gear and used to detect the water pressure entering the worm gear; the conductivity sensor being located at the inlet of the worm gear and used to detect the water conductivity entering the worm gear.

[0007] Furthermore, the first installation channel and the second installation channel are connected to the inside of the pipe along the radial direction of the pipe.

[0008] Furthermore, the socket has slots for mounting the conductive contacts, with the anode and the cathode respectively inserted into the slots.

[0009] Furthermore, a fixing bracket for fixing the anode and the cathode is fixedly connected to the socket, and the fixing bracket has a water passage gap that allows the anode and the cathode to contact the water in the pipe.

[0010] Furthermore, the socket is screwed into the first mounting channel.

[0011] Furthermore, the DC generator is screwed into the second mounting channel.

[0012] Furthermore, the surface of the anode is coated with a rare earth thick film.

[0014] Furthermore, a sealing ring is provided between the socket and the first mounting channel.

[0015] Furthermore, a sealing ring is provided between the DC generator and the second mounting channel.

[0016] Compared with the prior art, the present invention has the following advantages: The device uses a DC generator with adjustable blade spacing, which changes the amount of power generated in sync with the water pressure in the pipeline, ensuring that the silver ion generator can release a constant amount of silver ions and guarantee the purification effect.

[0022] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0023] like Figs. 1-3 As shown, a silver ion generating device includes: a housing 1, a pipe 2, a silver ion generator 3, a DC generator 4, and a sensing unit (not shown in the figure).

[0024] Pipe 2 is a one-piece molded pipe, and pipe 2 is fixedly connected inside the outer shell 1.

[0025] A first installation channel 21 and a second installation channel 22 are sequentially provided on the side wall of the pipe 2 along the direction of water flow. The first installation channel 21 and the second installation channel 22 are connected to the inside of the pipe 2 along the radial direction of the pipe.

[0026] The silver ion generator 3 is screwed into the first mounting channel 21. The silver ion generator 3 includes a socket 31, an anode 32 and a cathode 33. The socket 31 has conductive contacts that are electrically connected to the anode 32 and the cathode 33 respectively. In this embodiment, the anode 32 is a silver sheet and the cathode 33 is a graphite electrode.

[0027] In this embodiment, to facilitate the replacement of the depleted anode 32 and cathode 33, the socket 31 has two slots for installing conductive contacts, and the anode 32 and cathode 33 are respectively inserted into the slots. When the anode 32 and cathode 33 are worn out, they can be directly plugged in and replaced.

[0028] In this embodiment, to prevent the anode 32 and cathode 33 from shaking under the impact of water flow, a fixing bracket 34 for fixing the anode 32 and cathode 33 is fixedly connected to the socket 31. The fixing bracket has a water passage gap that allows the anode and cathode to contact the water in the pipe.

[0029] In this embodiment, a sealing ring is provided on the peripheral sidewall of the socket 31 to prevent water leakage.

[0030] During the electrolysis of silver ions in aqueous solution, an oxygen evolution reaction occurs, reducing the production of silver ions. Under high current density, silver ions on the anode silver plate easily form a black passivation layer (Ag2O / AgO), which also hinders the production of silver ions.

[0031] The main reaction sent by the anode silver sheet: Ag—Ag + +e - Oxygen evolution reaction: 2H₂O → O₂ + 4H₂O + +4e - .

[0032] In this embodiment, to address the issue of reduced silver ion generation, a rare earth film of approximately 200 nm (CeO2) is deposited on the anode silver sheet (approximately 5 mm from the conductive contact). The purpose is to reduce the oxygen evolution overpotential, decrease the shunt current of the anode side reaction, and improve the silver dissolution efficiency.

[0033] The DC generator 4 is fixedly connected to the second mounting channel 22, and there is a sealing ring between the DC generator 4 and the second mounting channel 22.

[0034] The DC generator 4 includes a worm gear with blades 41 whose spacing can be adjusted according to different inlet water pressures. The DC generator 4 provides power to the silver ion generator. In this embodiment, the DC generator 4 uses a motor of model ZLJ-02-001-M26 manufactured by Xiamen Zhilin Home Kitchen & Bath Technology Partnership (Limited Partnership). The motor turbine is axial-flow type (suitable for low-pressure inlet and high-flow-outlet applications). Its blades are designed with fluid dynamics in mind, and the spacing of the blades can be adjusted according to different inlet water pressures, thereby regulating the output voltage (the voltage can be increased at low water pressure and decreased at high water pressure, ensuring output within a set range). The related circuit connections, structure, and control of this DC generator are known technologies and will not be described in detail here.

[0035] The sensing unit is electrically connected to the DC generator; the sensing unit includes a water pressure sensor and a conductivity sensor. The water pressure sensor is located at the inlet of the worm gear and is used to detect the water pressure entering the worm gear; the conductivity sensor is located at the inlet of the worm gear and is used to detect the water conductivity entering the worm gear.

[0036] When the water pressure sensor detects low water pressure, it sends a signal to the control board, which then adjusts the spacing between the worm gear blades of the DC generator. This wider spacing (four blades are adjustable) results in higher rotational efficiency and greater power generation. Conversely, when the water pressure is high, the blade spacing is narrower, leading to lower rotational efficiency and less power generation.

[0037] Specifically, when the water pressure sensor detects a water pressure lower than 0.1 MPa or higher than 0.4 MPa, and the conductivity sensor detects a water conductivity in the pipe lower than 80 μS / cm or higher than 800 μS / cm, the spacing of the worm gear blades is adjusted accordingly.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
