Description

Technical Field

[0001] The utility model relates to the technical field of electrolyzed water. Background Art

[0002] With the increasing awareness and popularization of health, people's demand for sterilization and disinfection in their daily lives has gradually increased, and the demand for disinfection of existing electrical equipment on the market has also increased. Currently, portable disinfection spray bottle products have appeared on the market. For example, patents 202020273544.6 disclose an electrolytic cell, and 202010150913.7 disclose a disinfection spray bottle including an electrolytic cell. The spray bottle includes a connected nozzle and a bottle body. The bottle body is provided with a water storage chamber and an ozone generating chamber. A partition is provided between the water storage chamber and the ozone generating chamber, and an opening is provided in the partition to connect the water storage chamber and the ozone generating chamber. The ozone generating chamber is equipped with an ozone generator. The nozzle is connected to a straw that extends into the ozone generating chamber through the opening. The ozone generator's diamond anode, proton exchange membrane, and stainless steel cathode are fixed in sequence from bottom to top in an electrode plate holder. The straw guides the ozone water in the ozone generating chamber for spraying. Although this spray bottle has the advantages of compact structure, easy portability, safety and reliability, and the partition set can obtain high-concentration ozone water, due to structural problems of the ozone generating chamber and the ozone generator, the produced ozone and hydrogen are easily mixed, making the concentration of the ozone water unstable and affecting the sterilization and disinfection effect.

[0019] In one embodiment, the water electrolysis module is disposed on the communication port, and the communication port is located at the bottom of the water tank.

[0020] The beneficial effects of the utility model are:

[0021] The ion exchange membrane separates the first cavity and the second cavity, and the first cavity and the second cavity are connected only through the gap formed, wherein the second electrode can movably cover the gap so that the second electrode can movably approach or move away from the surface of the ion exchange membrane.

[0022] The electrolytic water module of this embodiment is suitable for use in appliances such as spray bottles and watering pots, and is connected to a module that can generate negative pressure at the water outlet. For example, the electrolytic water module of this application is applied to a spray bottle, and the electrolytic water module is connected to a straw on one side of the second electrode. When the spray bottle is pressed, the air is squeezed out, and the straw generates negative pressure suction. The movable second electrode is slightly displaced toward the low-pressure side under the action of the negative pressure suction. It should be understood that the second electrode is at least partially fixedly connected to achieve installation. Therefore, the second electrode achieves limited movement under negative pressure, and the water in the water inlet flows toward the water outlet due to the negative pressure suction and flows through the electrode stack. That is, the water flows from the direction of the first electrode and flows toward the second electrode through the gap of the ion exchange membrane. The second electrode moves slightly under negative pressure, creating a tiny gap for water to flow. That is, the second electrode no longer covers the gap during activity, creating a flow path for water to flow. Among them, the products on both sides of the ion exchange membrane are oxidized radical water on the anode side and hydrogen-rich water on the cathode side. Since the first cavity and the second cavity are connected only through the gap, and the ion exchange membrane only allows H + By preventing the water between the ion exchange membrane and the electrodes from passing through the membrane to the other side, the mixing of the products at the two electrodes can be effectively reduced. The products on the second electrode side flow downstream, while the products on the first electrode side are largely blocked in the first chamber and rise to the top of the water tank to converge. As a result, the generated oxidized group water or hydrogen-rich water is transported through the straw and sprayed out through the press nozzle for use. Due to the separation of the products, the product concentration is effectively increased, and the products are quickly transferred, improving the concentration and purity of the oxidized group water / hydrogen-rich water.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figure 1 and Figure 2 As shown, it is an electrolysis water module of a preferred embodiment of the utility model, specifically, it includes a shell 10 with an electrolysis chamber, an electrode stack 6 is arranged in the electrolysis chamber, the electrode stack 6 includes a first electrode 7, an ion exchange membrane 8 and a second electrode 9, the ion exchange membrane 8 separates the electrolysis chamber into a first cavity 61 and a second cavity 62, the first electrode 7 is arranged in the first cavity 61, and the second electrode 9 is arranged in the second cavity 62.

[0031] A gap 12 is defined between the ion exchange membrane 8 and the sidewall of the electrolysis chamber. The first cavity 61 and the second cavity 62 are connected via the gap 12 . The second electrode 9 can movably cover the gap 12 .

[0032] In this embodiment, the water electrolysis module includes a housing 10 and a first electrode 7, an ion exchange membrane 8, and a second electrode 9. The ion exchange membrane 8 is disposed in the housing 10, separating the electrolysis chamber of the housing 10 into a first cavity 61 and a second cavity 62, that is, the two sides of the ion exchange membrane 8 are the first cavity 61 and the second cavity 62, respectively. The housing 10 is used to install the electrode stack 6 to achieve at least partial fixed position of the first electrode 7, the ion exchange membrane 8, and the second electrode 9, and there is a gap 12 between the ion exchange membrane 8 and the housing 10, and the first cavity 61 and the second cavity 62 are connected through the gap 12. In order to achieve at least partial fixed position, for example, one end of the first electrode 7, the ion exchange membrane 8, and the second electrode 9 are mounted on the housing 10 by screws to achieve partial installation. This embodiment is not described in detail.

[0033] In which, the second electrode 9 can movably cover the gap 12, that is, the second electrode 9 can be movably arranged on the side of the ion exchange membrane 8. In order to realize that the second electrode 9 can movably cover the gap 12, for example, one side of the second electrode 9 is fixedly connected, and the other side of the second electrode 9 is movable, for example, an elastic part is pressed on the second electrode 9, thereby realizing the elastic movement of the second electrode 9 to movably cover the gap 12.

[0034] The beneficial effects of this embodiment are:

[0035] The ion exchange membrane 8 separates the first cavity 61 and the second cavity 62, and the first cavity 61 and the second cavity 62 are connected only by the gap 12 formed therebetween, wherein the second electrode 9 can movably cover the gap 12 (that is, it is movably set on the side of the ion exchange membrane 8), so that the second electrode 9 can movably approach or move away from the surface of the ion exchange membrane 8.

[0036] The electrolysis water module of this embodiment is suitable for use in appliances such as spray bottles and watering cans, wherein the water outlet is connected to a module that can generate negative pressure. For example, the electrolysis water module of this embodiment is applied to a spray bottle, and the electrolysis water module is connected to a straw on the side of the second electrode 9 (i.e., downstream in the direction of water flow). The air in the spray bottle is squeezed out by pressing, and the straw 45 generates negative pressure suction, or other modules that can generate negative pressure. Among them, the movable second electrode 9 is slightly displaced toward the low pressure side under the suction of the negative pressure. It should be understood that the second electrode 9 is at least partially fixedly connected to achieve installation. Therefore, the second electrode 9 achieves limited movement under negative pressure, and the water in the water inlet flows toward the water outlet due to the negative pressure suction, flowing through the electrode stack 6, that is, the water flows from the direction of the first electrode 7, through the gap 12 of the ion exchange membrane 8 and flows to the second electrode 9. The second electrode 9 moves slightly under the negative pressure state, creating a tiny gap for water to flow. That is, the second electrode 9 no longer covers the gap 12 during movement, creating a flow path for water to flow. Among them, the products on both sides of the ion exchange membrane 8 are respectively the oxidized radical water on the anode side and the hydrogen-rich water on the cathode side. Since the first cavity 61 and the second cavity 62 are only connected through the gap 12, and the ion exchange membrane 8 only allows H + By doing so, the water between the ion exchange membrane 8 and the electrode will not pass through the membrane to the other side, which can effectively reduce the mixing of the products at the two electrodes. The products on the second electrode 9 side (oxidized group water or hydrogen-rich water) flow downstream, while the hydrogen bubbles or oxygen bubbles on the first electrode 7 side are mostly blocked in the first cavity 61 due to the structural setting of the membrane and the second electrode. The blocked bubble products converge and rise to the top of the first cavity 61 (the converged gas can be discharged by changing the water or setting an exhaust port on the top). Since the products are separated, the product concentration is effectively improved, and the products are quickly transferred, thereby improving the concentration and purity of the oxidized group water / hydrogen-rich water.

[0037] Under the same conditions, the electrolysis water module of the present application: (1) the output at the water outlet is oxygen. If the concentration of the oxidized water produced by the hybrid electrolysis water module is 1 mg / L, the output of the present application can reach 1.3 mg / L, which effectively increases the concentration by 30%; (2) the output at the water outlet is hydrogen. If the hydrogen concentration of the hybrid electrolysis water module reaches 600 ppb, the output of the present application can reach 780 ppb, which effectively increases the concentration by 30%. In addition, because the ratio of hydrogen to oxygen in the anode and cathode products is approximately 2:1, the separation of the anode and cathode products can significantly reduce bubbles in the water outlet, greatly reducing the water hammer impact effect caused by gas in the pipeline.

[0038] Among them, the ion exchange membrane 8 should separate the space on both sides of the membrane so that it can flow only through the gap 12 on the ion exchange membrane 8. Therefore, the electrolytic water module should be set at a position that can achieve the separation of space. For example, the ion exchange membrane 8 is connected to the side wall of the electrolysis chamber, and the rest of the parts except the gap 12 are tightly connected to achieve separation.

[0039] It should be understood that the first electrode 7 and the second electrode 9 are connected to an external power supply voltage, and the polarity of the first electrode 7 and the second electrode 9 is determined by the power supply to which they are connected. The electrode connected to the positive pole of the power supply is the positive pole, and the electrode connected to the negative pole of the power supply is the cathode. In addition, the water electrolysis module in this application can reverse the polarity so that the output product is oxidized group water or hydrogen-rich water.

[0040] In order to construct a water flow channel, for example, a water inlet hole is provided on the first electrode 7, and the water inlet is connected to the gap. For another example, a water inlet notch is provided on the first electrode 7, and the water inlet notch is connected to the gap, so that the water inlet end can flow into the gap 12 through the first electrode 7.

[0041] To construct a water flow channel, in one embodiment, the first electrode 7 is staggered with respect to the gap 12 so that the water inlet can flow into the gap 12 through the first electrode 7 .

[0042] In one embodiment, the direction of water flow at the water outlet is inclined or perpendicular to the direction of the electrode plates of the electrode stack 6. Preferably, the direction of water flow at the water outlet is perpendicular to the direction of the electrode plates of the electrode stack 6, so that the negative pressure suction force acting on the second electrode 9 at the water outlet can cause it to move to the greatest extent. In this embodiment, no detailed description is required.

[0043] In one embodiment, the electrode stack 6 is arranged vertically, and the gap 12 is formed at the bottom of the ion exchange membrane 8. Hydrogen is generated on the electrode surface. Hydrogen is light in weight and easily floats and gathers in water. During the floating process, it is blocked by the membrane and electrode sheets, making it more difficult for hydrogen to mix with the oxygen-end gas.

[0044] In one embodiment, the electrode material of the first electrode 7 and / or the second electrode 9 is conductive silicon, conductive diamond, or one of titanium, platinum, lead, tantalum, iridium, palladium, or their oxides. In one embodiment, the first electrode 7 is a cathode, and the material of the first electrode 7 can be platinum, stainless steel, titanium, etc. The second electrode 9 is an anode, and the material of the second electrode 9 can be conductive silicon, conductive diamond, or one of titanium, platinum, lead, tantalum, iridium, palladium, or their oxides, or other conductive materials. In one embodiment, the electrode material of the first electrode 7 and the second electrode 9 is the same, and the electrode conversion between the first electrode 7 and the second electrode 9 can be achieved by converting the current.

[0045] The sizes and shapes of the first electrode 7 , the ion exchange membrane 8 and the second electrode 9 can be set according to actual needs.

One end of the straw 45 is connected to the nozzle 1, and the other end of the straw 45 is connected to the water tank 3. When the nozzle 1 is not pressed, that is, the suction pipe 45 is not under negative pressure, the second electrode 9 is attached to the surface of the ion exchange membrane 8, and the second electrode 9 covers the gap 12. When the pressing nozzle 1 is pressed, the air in the straw 45 is squeezed out to form a negative pressure suction. Under the action of the negative pressure suction, the second electrode 9 will slightly shift toward the low-pressure side, creating a tiny gap for water to flow. In other words, the second electrode 9 no longer covers the gap 12 during movement, creating a flow path for water to flow.

[0049] In one embodiment, the nozzle 1 and the bottle body 2 are detachably connected, and the bottle body 2 can be easily disassembled and filled with water into the water tank 3. For example, the water tank 3 is arranged at the top of the bottle body 2, and the water tank 3 is provided with a water inlet opening.

The user fills the water tank 3 with water, so that the water tank 3 can be set at the top of the bottle body 2, with a large opening for convenient water filling, and the electrolysis water module can be According to design requirements, it can be conveniently arranged at the bottom of the water tank 3 or near the bottom (the second straw 45 or the connecting point). Other electronic components (such as power supplies and circuit boards) can be integrated in the electronic component area near the water tank 3 to facilitate electrical connection with the electrolytic water module, thereby avoiding the problem of large volume or small capacity of the water tank 3 caused by complex circuits that occupy the effective capacity of the bottle body 2. In addition, the electrolysis module is set in the flow path of the water flow, and the product is quickly taken away, which can effectively increase the concentration and avoid the problem of low concentration caused by the dispersion of the product in the water body of the water tank 3.

[0057] It should be understood that the embodiment of the present application does not limit the arrangement direction of the electrode stack 6.
