Description

Technical Field

[0001] This utility model belongs to the field of household appliance technology, and in particular relates to an air-powered module and a household appliance. Background Technology

[0002] Currently, water heaters are common household appliances, categorized into electric water heaters, heat pump water heaters, and solar water heaters. Electric water heaters are widely used due to their convenience. Among them, storage-type electric water heaters, equipped with a water tank, offer advantages such as large water output and stable water temperature, making them increasingly popular with families.

[0003] A typical storage-type electric water heater usually consists of a water tank, an electric heating element, and an electronic control board. The water tank is typically treated with anti-corrosion measures to protect the inner tank from corrosion, usually achieved by adding a magnesium rod or an external electron anode. Using an external electron anode for corrosion protection avoids the scale buildup that can occur with magnesium rods.

[0004] In practical use, external electronic anodes require power supply. Chinese Patent Publication No. CN107408744A discloses a catalyst system for advanced metal-air batteries, comprising a metal anode; a cathode containing at least one transition metal dichalcogenide; and an electrolyte in contact with the transition metal dichalcogenide of the anode and cathode. During use, electrochemical reactions lead to the continuous loss of zinc and the generation of chemical reactants. These chemical reactant deposits can obstruct one side of the anode, reducing the contact area between the anode and the electrolyte and affecting power generation efficiency. Therefore, designing a technology to improve power generation performance is the technical problem this invention aims to solve. Utility Model Content

[0072] Water heaters are common household appliances, with those equipped with water tanks being the most widely used. Common types of water heaters with water tanks include electric water heaters and heat pump water heaters, differing primarily in their heating methods. During use, the water tank also requires anti-corrosion treatment. Let's take an electric water heater as an example.

[0073] An electric water heater is a type of water heater that uses electricity as its primary energy source. The high-temperature heat generated after the power is turned on directly heats the water stored in the water heater to produce hot water.

[0074] Electric water heaters typically consist of a water tank, an electric heating element, and an electronic control board. The water tank has a storage cavity to store water to be heated. The electric heating element is inserted into the storage cavity of the water tank. The electronic control board is used to control the electric heating element to operate by turning the power on and off, so that the water in the tank is heated to the set temperature.

[0075] For the water tank of an electric water heater, the tank generally consists of an outer shell and an inner tank, with an insulation layer between them. The outer shell is usually made of plastic to meet the requirements of aesthetic and diverse designs; the inner tank can be made of metal or plastic, depending on the needs.

[0076] In addition, the insulation layer formed between the outer shell and the inner liner is commonly made of materials such as asbestos, sponge, foam plastic, and polyurethane foam. In conventional technology, foaming is usually used to form the insulation layer in order to achieve good insulation effect.

[0077] The water tank is also equipped with an inlet pipe and an outlet pipe. The inlet pipe is used to deliver cold water into the water storage cavity formed inside the water tank, while the hot water in the water storage cavity is output from the outlet pipe.

[0078] For electric heating components, electric heating methods such as electric heating wires, magnetic energy, or silicon tube heating can be used to heat the water stored in the water storage chamber.

[0079] The control board is used to receive detection signals from relevant sensors (such as water temperature sensors and flow sensors) and control the power supply to and from the electric heating components.

[0080] When the electric water heater is working, the electric control board controls the electric heating element to be powered on and heated. When the water temperature in the tank reaches the set value, the electric control board controls the electric heating element to be powered off.

[0081] For water tanks with metal inner liner, corrosion can easily occur inside due to water quality. Therefore, magnesium rods are installed on the water tank and inserted into the water storage cavity inside the tank.

[0082] Alternatively, an electronic anode can be used to treat the inner liner for corrosion protection. During use, the electronic anode requires a power supply.

[0083] In Example 1, to overcome the problem that the electron anode cannot function properly when the power plug is unplugged from the socket when using the user's home mains power, one embodiment of this application uses an air-powered module to power the electron anode. To ensure a longer service life for the air-powered module, the following structural improvements are made to the air-powered module.

[0084] like Figures 1-5 As shown, this embodiment provides an air-powered module, including:

[0085] The outer casing 1 has a liquid storage cavity 11 formed therein. The outer casing 1 is also provided with an installation port 12 communicating with the liquid storage cavity 11. A cathode film 13 is provided in the outer casing 1, and the cathode film 13 seals and covers the installation port 12. The liquid storage cavity 11 is filled with electrolyte.

[0086] Metal anode 2, wherein the metal anode 2 is disposed in the outer casing 1;

[0087] Electrode assembly 3 includes a first electrode 31 and a second electrode 32, which are respectively disposed on the outer casing 1. The first electrode 31 is electrically connected to the cathode film 13, and the second electrode 32 is electrically connected to the metal anode 2. The first electrode 31 and the second electrode 32 are arranged back to back.

[0088] Specifically, the air-powered module provided in this application forms a liquid storage cavity 11 in the outer casing 1 to be filled with electrolyte. The outer casing 1 has an mounting port 12 to allow the cathode film 13 to contact the outside air. The cathode film 13 seals the mounting port 12 and is electrically connected to the first electrode 31. The cathode film 13 can be made of materials such as activated carbon or graphene; the specific physical form of the cathode film 13 is not limited here.

[0089] The metal anode 2 is disposed within the outer casing 1 and located within the liquid storage cavity 11, positioned away from the cathode film 13. The metal anode 2 undergoes an electrochemical reaction in the electrolyte, thereby creating a potential difference between the first electrode 31 and the second electrode 32 to supply power. The metal anode 2 can be made of materials such as aluminum, magnesium, or zinc; no specific material is limited thereto.

[0090] By placing a metal anode 2 inside the outer casing 1 as a consumable for the electrochemical reaction, the outer casing 1 has a large space to install a large-sized metal anode 2. In addition, the outer casing 1 can be filled with sufficient electrolyte. In this way, during actual use, the metal anode 2 undergoes an electrochemical reaction in the electrolyte to generate electrical energy, thereby extending the battery life and meeting the requirements for long-term power supply and current corrosion prevention. Users do not need to replace batteries frequently, thus improving the user experience.

[0091] More importantly, the first electrode 31 and the second electrode 32 are arranged in opposite directions, which allows for the use of conventional battery installation methods for final connection according to the power supply voltage requirements during actual use, thereby increasing the total power supply voltage to meet the requirements for current corrosion prevention.

[0092] In one embodiment, the outer shell 1 is further provided with an exhaust hole 14, and the exhaust hole 14 is provided with a waterproof and breathable component 15;

[0093] The waterproof and breathable component 15 is configured to prevent water from flowing out of the liquid storage cavity 11 and to allow gas in the liquid storage cavity 11 to be discharged to the outside of the outer shell 1.

[0094] Specifically, for the metal anode 2, hydrogen gas is generated during the chemical reaction in the electrolyte. To ensure safe use by timely venting the hydrogen gas in the storage chamber 11, a vent 14 is provided on the outer casing 1, and a waterproof and breathable component 15 is provided on the vent 14. The waterproof and breathable component 15 can meet the requirement of normal venting of hydrogen gas in the storage chamber 11 to the outside, and at the same time, it can prevent electrolyte leakage in the storage chamber 11, thereby ensuring that the air-powered module can be used for a long time.

[0095] In some embodiments, the waterproof and breathable component 15 includes a first membrane 151 disposed outside the vent 14.

[0096] The first diaphragm 151 is configured to block the outflow of water from the liquid storage chamber 11 and allow gas in the liquid storage chamber 11 to pass through and be discharged.

[0097] Specifically, in order to meet the requirements of breathability and water leakage prevention, the waterproof and breathable component 15 includes a first membrane 151, which covers the vent 14 to allow hydrogen gas in the liquid storage chamber 11 to be discharged and to prevent electrolyte leakage in the liquid storage chamber 11.

[0098] The specific physical manifestation of the first membrane 151 can be a membrane with breathable and waterproof functions in conventional technology, such as a waterproof and breathable membrane.

[0099] In some embodiments, in order to facilitate the installation of the first diaphragm 151, the exhaust hole 14 is further provided with an installation component 153, and the installation component 153 is provided with a through hole 1531;

[0100] The mounting component 153 is sealed in the vent hole 14, and the through hole 1531 communicates with the liquid storage cavity 11.

[0101] The first diaphragm 151 is disposed on the mounting component 153 and seals and covers the through hole 1531.

[0102] Specifically, in order to facilitate the installation of the first diaphragm 151 on the vent 14, the installation requirements of the first diaphragm 151 can be met by the mounting component 153. The mounting component 153 has a through hole 1531. The mounting component 153 is inserted into the vent 14 so that the through hole 1531 communicates with the liquid storage chamber 11. The first diaphragm 151 covers the through hole 1531 on the mounting component 153.

[0103] In some embodiments, the waterproof and breathable component 15 includes a second membrane 152, which is attached to the first membrane.

[0104] The second diaphragm 152 is configured to block the outflow of water vapor from the liquid storage chamber 11 and allow hydrogen gas from the liquid storage chamber 11 to pass through and be discharged.

[0105] Specifically, to more effectively extend the service life of the air-powered module and prevent water vapor in the storage chamber 11 from being released to the outside through the first diaphragm 151, thus preventing premature drying of the electrolyte in the storage chamber 11, the second diaphragm 152 can block water vapor from being released from the storage chamber 11. This ensures that the electrolyte in the storage chamber 11 can be used for a longer period of time, while still meeting the requirements for normal hydrogen emission, thereby extending the service life of the air-powered module.

[0106] Meanwhile, when the water heater is used in a high-humidity environment, the second diaphragm 152 can also prevent external water vapor from entering the liquid storage chamber 11, thereby effectively ensuring that the concentration of the electrolyte is kept within a reasonable range, so as to extend the service life of the air-powered module.

[0107] The physical form of the second membrane 152 can be a membrane that is permeable to hydrogen and blocks water vapor, such as hydrogen evolution membrane, hydrogen separation membrane, water vapor barrier membrane, etc., which are not limited or elaborated here.

[0108] In addition, the second membrane 152 is disposed inside the first membrane 151; at this time, the second membrane is also configured to prevent water vapor between the first membrane and the second membrane from entering the liquid storage cavity.

[0109] Alternatively, the second membrane is disposed outside the first membrane; the second membrane is also configured to prevent water vapor from outside the housing from entering the liquid storage cavity.

[0110] Similarly, for the second diaphragm 152, both the second diaphragm 152 and the first diaphragm 151 are mounted on the mounting component 153.

[0111] In addition, the mounting component 153 may be provided with a claw, and the mounting component 153 is engaged in the vent hole 14 by means of the claw; and in order to meet the requirement of sealing connection between the mounting component 153 and the vent hole 14, a sealing ring may also be provided between the mounting component 153 and the outer shell 1 to meet the requirement of sealing the vent hole 14.

[0112] Alternatively, the mounting component 153 may have an external thread, and the vent hole 14 may have a threaded hole, with the mounting component 153 threadedly connected to the vent hole 14.

[0113] Furthermore, in order to protect the diaphragm, the mounting component 153 is also provided with a removable protective cover 1532, which covers the outside of the waterproof and breathable component 15.

[0114] Specifically, a protective cover 1532 is disposed on the mounting component 153 to cover the outside of the first diaphragm 151, and there is a gap between the protective cover 1532 and the first diaphragm 151 to meet the requirements of air permeability.

[0115] In one embodiment, the housing 1 is provided with a mounting and fixing part 16, and the metal anode 2 is fixedly mounted in the housing 1 through the mounting and fixing part 16.

[0116] Specifically, for the metal anode 2, in order to securely and reliably install it inside the liquid storage chamber 11 of the outer casing 1, a mounting and fixing part 16 can be provided inside the outer casing 1. The mounting and fixing part 16 can securely install the metal anode 2 inside the outer casing 1. This ensures that the metal anode 2 can be securely and reliably installed inside the outer casing 1 during use.

[0117] Wherein, the mounting and fixing part 16 is a baffle formed on the inner wall of the outer shell 1, and the metal anode 2 is sandwiched between the baffle and the end of the outer shell 1; or, the mounting and fixing part 16 is an elastic pressure plate provided on the inner wall of the outer shell 1, and the elastic pressure plate presses the metal anode 2 against the end of the outer shell 1.

[0118] In addition, the outer casing 1 can be cylindrical, with a metal anode 2 arranged at one end and a cathode film 13 arranged at the other end.

[0119] In order to improve the power supply capacity and provide sufficient voltage to meet the requirements of current corrosion prevention, the air power supply module includes multiple housings 1, and each housing 1 is provided with a metal anode 2 and an electrode assembly 3.

[0120] During use, the first electrode 31 on one housing 1 is connected to the second electrode 32 on the other housing 1 to achieve a series connection, thereby meeting the requirements for power supply voltage.

[0121] To facilitate series connection, one end of the outer casing 1 is provided with the first electrode 31, and the other end of the outer casing 1 is provided with the second electrode 32; the air power supply module also includes a mounting shell (not shown), in which multiple outer casings 1 are provided; among two adjacent outer casings 1, the first electrode 31 on one outer casing 1 is in contact with the second electrode 32 on the other outer casing 1 for conductive connection.

[0122] Specifically, when multiple outer shells 1 are connected in series, two adjacent outer shells 1 are placed close together so that the first electrode 31 makes contact with the second electrode 32 on another outer shell 1, thereby satisfying the series electrical connection requirements in the circuit. At the same time, multiple outer shells 1 are assembled into the same mounting shell, which is used to position and install the multiple outer shells 1. Then, they are all installed onto the water heater through the mounting shell for easy assembly and use.

[0123] In another embodiment, the air-powered module further includes conductive foam 17, which is attached to the cathode film 13.

[0124] Specifically, since the cathode film 13 needs to be in contact with air to meet the requirements of the electrochemical reaction, the contact area between the cathode film 13 and the air also determines the power supply performance of the air-powered module. To ensure reliable installation of the cathode film 13 and sufficient contact between it and the air, conductive foam 17 can be placed on the outside of the cathode film 13. The conductive foam 17 is sandwiched between the cathode film 13 and the mounting opening 12, and its porous structure ensures that different parts of the cathode film 13 can fully contact the air.

[0125] Furthermore, the conductive foam 17 can also support the cathode film 13. A mounting bracket 18 can be provided inside the housing 1 to press the cathode film 13 and the conductive foam 17 firmly onto the end face of the housing 1 with the mounting opening 12. The conductive foam 17 can provide good support for the cathode film 13 from the outside. Simultaneously, the conductive foam 17, positioned on the outside of the cathode film 13, can also protect it from the outside.

[0126] Example 2, as Figures 6-12 As shown, this application also provides an air-powered module, including:

[0127] The outer casing 1 includes a first housing 101, a second housing 102, and a cathode membrane 13. The first housing 101 is provided with an installation port 12. The cathode membrane 13 is disposed on the first housing 101 and seals and covers the inner side of the installation port 12. The first housing 101 and the second housing 102 are connected together. A liquid storage cavity 11 is formed inside the outer casing 1 on the inner side of the cathode membrane 13, and the liquid storage cavity 11 is filled with electrolyte.

[0128] Metal anode 2, wherein the metal anode 2 is disposed in the second housing 102;

[0129] Electrode assembly 3 includes a first electrode 31 and a second electrode 32. The first electrode 31 is disposed on the first housing 101 and electrically connected to the cathode film 13, and the second electrode 32 is disposed on the second housing 102 and electrically connected to the metal anode 2.

[0130] Specifically, the air-powered module provided in this application has a split-type housing 1, which is assembled from a first housing 101 and a second housing 102. The first housing 101 is used to install the cathode membrane 13, and the first housing 101 is provided with an installation port 12 for the cathode membrane 13 to contact with the outside air. The cathode membrane 13 seals and covers the installation port 12. At the same time, the first electrode 31 is disposed on the first housing 101, and the first motor is electrically connected to the cathode membrane 13.

[0131] The second housing 102 is used to install the metal anode 2. At the same time, the second electrode 32 is disposed on the second housing 102, and the second motor is electrically connected to the metal anode 2.

[0132] After the first housing 101 and the second housing 102 are assembled together, a liquid storage cavity 11 will be formed between the first housing 101 and the second housing 102. The liquid storage cavity 11 is filled with electrolyte, which will simultaneously contact the metal anode 2 and the cathode film 13. The metal anode 2 undergoes an electrochemical reaction in the electrolyte, thereby creating a potential difference between the first electrode 31 and the second electrode 32 to achieve external power supply.

[0133] The cathode film 13 can be made of materials such as activated carbon and graphene; the specific physical form of the cathode film 13 is not limited here. The metal anode 2 can be made of materials such as aluminum, magnesium, or zinc; there are no restrictions on its physical form.

[0134] By designing the outer casing 1 as a separate unit, the two casings respectively meet the installation requirements of the cathode film 13 and the metal anode 2. When the two casings are assembled together, they form a large liquid storage cavity 11 to accommodate the installation of a large-sized metal anode 2 and to fill it with sufficient electrolyte. In this way, during actual use, the metal anode 2 undergoes an electrochemical reaction in the electrolyte to generate electrical energy, thereby extending the battery life and meeting the requirements for long-term power supply and current corrosion prevention. Users do not need to replace the battery frequently, thus improving the user experience.

[0135] In one embodiment, a fixing frame 19 is provided in the first housing 101. The fixing frame 19 is fixedly disposed in the first housing 101 and the fixing frame 19 seals and presses the edge of the cathode film 13 against the inner wall of the first housing 101.

[0136] Specifically, in order to fix the cathode membrane 13 in the first housing 101, a fixing frame 19 can be provided in the first housing 101. The fixing frame 19 can press the cathode membrane 13 onto the end face of the first housing 101 with the installation port 12 to ensure reliable installation and fixation of the cathode membrane 13.

[0137] In one embodiment of this application, in order to ensure safety and reliability during use and to prevent electrolyte leakage due to damage to the cathode film 13, the following structural improvements are made to the outer casing 1.

[0138] The outer casing 1 has a liquid storage chamber 11 and an air chamber 100, which are connected by a mounting port 12. A cathode film 13 is also provided in the liquid storage chamber 11, which seals and covers the inside of the mounting port 12. A venting part 103 is also provided on the outer casing 1, which is connected to the air chamber 100 and is arranged on the upper part of the outer casing 1.

[0139] Specifically, during use, if the electrolyte in the storage cavity 11 leaks due to damage to the cathode membrane 13, the electrolyte will flow into the air cavity 100. The vent 103 of the air cavity 100, which is connected to the outside atmosphere, is arranged at the top of the outer shell 1, thereby preventing the electrolyte from leaking to the outside of the outer shell 1 and improving the reliability of use.

[0140] Typically, the air cavity 100 is arranged on the side or bottom of the housing 1.

[0141] Specifically, when the air cavity 100 is formed on the side of the outer casing 1, the vent 103 can be arranged on the upper part of the side wall or the top wall of the outer casing 1. When the air cavity 100 is formed on the bottom of the outer casing 1, the vent 103 can be arranged on the upper part of the side wall or the top wall of the outer casing 1, and the vent 103 can be connected to the air cavity 100 at the bottom through an air pipe or the like.

[0142] By providing a liquid storage chamber 11 and an air chamber 100 on the outer casing 1, the air chamber 100 can meet the requirements for the cathode membrane 13 to contact with the outside air through the vent 103. By arranging the vent 103 in the upper region of the outer casing 1, in the event of leakage of electrolyte in the liquid storage chamber 11 due to damage to the cathode membrane 13, the leaked electrolyte will flow into the air chamber 100 to be mixed with the leaked electrolyte. At the same time, since the vent 103 is arranged in the upper region of the air chamber 100, the vent 103 is arranged above the electrolyte level to prevent electrolyte from leaking to the outside of the outer casing 1, thereby improving the reliability of use.

[0143] In one embodiment, the outer end face of the first housing 101 is formed with a mounting groove 1011, and the mounting opening 12 is located in the mounting groove 1011;

[0144] The outer casing 1 also includes a cover plate 104, which is disposed on the outer end face of the first casing 101 and covers the mounting groove 1011. An air cavity 100 is formed between the first casing 101 and the cover plate 104.

[0145] A vent 103 is provided on the first housing 101 or the cover plate 104, and the vent 103 is in communication with the air cavity 100.

[0146] Specifically, in order to facilitate the formation of the air cavity 100, a mounting groove 1011 is formed on the first housing 101, and a mounting opening 12 is formed in the mounting groove 1011. The mounting groove 1011 is covered by a cover plate 104 to form the air cavity 100.

[0147] As for the vent 103, the vent 103 can be formed on the top of the first housing 101, or the vent 103 can be formed on the upper part of the cover plate 104.

[0149] Specifically, when the vent 103 is provided on the cover plate 104, the vent 103 is a second vent notch provided on the top edge of the cover plate 104, or the vent 103 is a second vent hole provided on the upper part of the cover plate 104.

[0150] Furthermore, a support rib 1012 is provided in the mounting groove 1011, and the support rib 1012 abuts against the inner surface of the cover plate 104.

[0151] Specifically, in order to reliably form the air cavity 100, a support rib 1012 can be provided in the mounting groove 1011 to support the column cover plate 104, so that the cover plate 104 forms an air cavity 100 in the mounting groove 1011.

[0152] The cover plate 104 is designed to form an independent air cavity 100, and the cover plate 104 can also protect the cathode film 13 in the mounting port 12.

[0153] Furthermore, the support rib 1012 is arranged around the mounting opening 12, and the support rib 1012 also extends to the vent 103;

[0154] The support rib 1012 is configured to guide gas into and out of the air cavity 100 via the ventilation section 103.

[0155] Specifically, the support rib 1012 in the mounting groove 1011 is arranged around the periphery of the mounting opening 12, and the two ends of the support rib 1012 extend to the vent 103. In this way, the air cavity 100 and the outside atmosphere can communicate with each other through the vent 103 and the guide of the support rib 1012.

[0156] In one embodiment, the outer shell 1 is further provided with an exhaust hole 14, and the exhaust hole 14 is provided with a waterproof and breathable component 15;

[0157] The waterproof and breathable component 15 is configured to prevent water from flowing out of the liquid storage cavity 11 and to allow gas in the liquid storage cavity 11 to be discharged to the outside of the outer shell 1.

[0158] Specifically, for the metal anode 2, hydrogen gas is generated during the chemical reaction in the electrolyte. To ensure safe use by timely venting the hydrogen gas in the storage chamber 11, a vent 14 is provided on the outer casing 1, and a waterproof and breathable component 15 is provided on the vent 14. The waterproof and breathable component 15 can meet the requirement of normal venting of hydrogen gas in the storage chamber 11 to the outside, and at the same time, it can prevent electrolyte leakage in the storage chamber 11, thereby ensuring that the air-powered module can be used for a long time.

[0159] The vent 14 can be provided on the first housing 101 or the second housing 102.

[0160] In some embodiments, the waterproof and breathable component 15 includes a first membrane 151 disposed outside the vent 14.

[0161] The first diaphragm 151 is configured to block the outflow of water from the liquid storage chamber 11 and allow gas in the liquid storage chamber 11 to pass through and be discharged.

[0162] Specifically, in order to meet the requirements of breathability and water leakage prevention, the waterproof and breathable component 15 includes a first membrane 151, which covers the vent 14 to allow hydrogen gas in the liquid storage chamber 11 to be discharged and to prevent electrolyte leakage in the liquid storage chamber 11.

[0163] The specific physical manifestation of the first membrane 151 can be a membrane with breathable and waterproof functions in conventional technology, such as a waterproof and breathable membrane.

[0164] In some embodiments, in order to facilitate the installation of the first diaphragm 151, a cover component 141 is also provided in the vent 14, and the cover component 141 is provided with a vent hole (not marked).

[0165] The covering component 141 is disposed on the outside of the first diaphragm 151.

[0166] Specifically, a cover member 141 is disposed in the vent hole 14 to protect the outside of the first diaphragm 151. At the same time, in order to meet the venting requirements, a vent hole is provided on the cover member 141. Hydrogen gas in the liquid storage chamber 11 passes through the first diaphragm 151 and is discharged to the outside of the outer casing 1 through the vent hole.

[0167] In another embodiment, the waterproof and breathable component 15 includes a second membrane 152, which is disposed inside the first membrane 151.

[0168] The second diaphragm 152 is configured to block the outflow of water vapor from the liquid storage chamber 11 and allow hydrogen gas from the liquid storage chamber 11 to pass through and be discharged.

[0169] Specifically, to more effectively extend the service life of the air-powered module and prevent water vapor in the storage chamber 11 from being released to the outside through the first diaphragm 151, thus preventing premature drying of the electrolyte in the storage chamber 11, the second diaphragm 152 can block water vapor from being released from the storage chamber 11. This ensures that the electrolyte in the storage chamber 11 can be used for a longer period of time, while still meeting the requirements for normal hydrogen emission, thereby extending the service life of the air-powered module.

[0170] The physical form of the second membrane 152 can be a membrane that is permeable to hydrogen and blocks water vapor, such as hydrogen evolution membrane, hydrogen separation membrane, water vapor barrier membrane, etc., which are not limited or elaborated here.

[0171] In another embodiment of this application, in order to facilitate the installation and fixing of the metal anode 2, the second housing 102 is provided with an installation and fixing part 16, and the metal anode 2 is fixedly installed in the second housing 102 through the installation and fixing part 16.

[0172] Specifically, for the metal anode 2, in order to securely and reliably install it in the second housing 102, a mounting and fixing part 16 can be provided in the second housing 102. The mounting and fixing part 16 can securely install and fix the metal anode 2 in the second housing 102. This ensures that the metal anode 2 can be securely and reliably installed and fixed inside the outer housing 1 during use.

[0173] Furthermore, the mounting and fixing part 16 is a baffle formed on the inner wall of the second housing 102, and the metal anode 2 is sandwiched between the baffle and the end of the second housing 102; or, the mounting and fixing part 16 is an elastic pressure plate provided on the inner wall of the second housing 102, and the elastic pressure plate presses the metal anode 2 against the end of the second housing 102.

[0174] In another embodiment, the air-powered module further includes conductive foam 17, which is attached to the cathode film 13.

[0175] Specifically, since the cathode film 13 needs to be in contact with air to meet the requirements of the electrochemical reaction, the contact area between the cathode film 13 and the air also determines the power supply performance of the air-powered module. To ensure reliable installation of the cathode film 13 and sufficient contact between it and the air, conductive foam 17 can be placed on the outside of the cathode film 13. The conductive foam 17 is sandwiched between the cathode film 13 and the mounting opening 12, and its porous structure ensures that different parts of the cathode film 13 can fully contact the air.

[0176] Furthermore, the conductive foam 17 can also support the cathode film 13. A mounting bracket 18 can be provided inside the housing 1 to press the cathode film 13 and the conductive foam 17 firmly onto the end face of the housing 1 with the mounting opening 12. The conductive foam 17 can provide good support for the cathode film 13 from the outside. Simultaneously, the conductive foam 17, positioned on the outside of the cathode film 13, can also protect it from the outside.

[0177] Example 3, based on Examples 1 and 2, optionally, in order to improve the reliability of the metal anode 2 and avoid the chemical reactants generated by the reaction of the metal anode 2 due to gravity accumulating at the bottom and obscuring the front of the metal anode 2, thus affecting power generation.

[0178] The mounting and fixing part 16 provided in the liquid storage cavity 11 is configured to arrange the metal anode 2 above the bottom surface of the outer casing 1 such that a gap is formed between the metal anode 2 and the bottom surface of the outer casing 1.

[0179] Specifically, the mounting and fixing part 16 enables the metal anode 2 to be higher than the bottom surface of the outer casing 1, thereby creating a gap between the metal anode 2 and the bottom surface of the outer casing 1. During use, due to the electrochemical reaction that occurs on the metal anode 2, chemical reactants produced by the chemical reaction will continuously fall off the surface of the metal anode 2 and land on the bottom surface of the outer casing 1.

[0180] Because the metal anode 2 is higher than the bottom surface of the outer casing 1, the chemical reactants accumulated at the bottom of the outer casing 1 will not accumulate and cover the surface of the metal anode 2. This ensures that the metal anode 2 always has sufficient contact area with the electrolyte, guaranteeing the normal progress of the electrochemical reaction.

[0181] Furthermore, an insertion port 161 is provided on the inner wall of the outer casing 1, the insertion port 161 is located above the bottom surface of the outer casing 1, and the end of the metal anode 2 is inserted into the insertion port 161;

[0182] The socket 161 forms the mounting and fixing part 16.

[0183] Specifically, in order to facilitate the installation of the metal anode 2, an insertion port 161 can be provided on the inner wall of the outer casing 1, and the metal anode 2 is inserted into the insertion port 161 to complete the installation and fixation.

[0184] Furthermore, a positioning plate 162 is provided on the inner wall of the outer shell 1, and the positioning plate 162 is arranged opposite to the insertion port 161.

[0185] One end of the metal anode 2 is inserted into the socket 161, and the other end of the metal anode 2 is locked onto the positioning plate 162;

[0186] The socket 161 and the positioning plate 162 together form the mounting and fixing part 16.

[0187] Specifically, after inserting one end of the metal anode 2 into the socket 161, the other end of the metal anode 2 can be positioned and fixed by the positioning plate 162. In this way, both ends of the metal anode 2 can be effectively fixed and installed through the socket 161 and the positioning plate 162, allowing the metal anode 2 to be separated from the bottom surface of the outer casing 1.

[0188] Furthermore, in order to improve the reliability of electrical contact between the metal anode 2 and the second electrode 32, the second electrode 32 includes a conductive sheet 311 and a conductive base 312, the conductive sheet 311 and the conductive base 312 are electrically connected, the conductive base 312 is disposed in the socket 161, and the conductive sheet 311 extends to the outside of the outer casing 1.

[0189] One end of the metal anode 2 is electrically connected to the conductive base 312.

[0190] Specifically, during assembly, to improve ease of assembly, the conductive base 312 can be placed into the socket 161, with the conductive sheet 311 connected to the conductive base 312 extending outwards from the outer casing 1. After the metal anode 2 is inserted into the socket 161, the corresponding end of the metal anode 2 is tightly pressed against the conductive base 312, satisfying the assembly requirements for reliable electrical connection.

[0191] Alternatively, the mounting and fixing part 16 can also adopt other structural forms. For example, a claw is provided on the inner wall of the outer casing 1, and the metal anode 2 is clamped on the claw, the claw forming the mounting and fixing part 16; or, a mounting bracket is provided on the inner wall of the outer casing 1, the mounting bracket is fixedly installed on the inner wall of the outer casing 1, and the metal anode 2 is located between the mounting bracket and the inner wall of the outer casing 1, the mounting bracket forming the mounting and fixing part 16.

[0192] Example 4, as Figures 13-20 As shown, this application also provides a water heater, including:

[0193] Water tank 4, the water tank 4 includes a tank shell 41 and an inner liner 42, the inner liner 42 being disposed in the tank shell 41;

[0194] An electronic anode 5 is disposed in the inner liner 42;

[0195] A power supply module is used to supply power to the electronic anode 5.

[0196] Specifically, the water heater is equipped with a water tank 4 to store water, and an electronic anode 5 is installed in the inner tank 42 to meet the requirements of current anti-corrosion treatment of the inner tank 42. The power supply module can supply power to the electronic anode 5 to meet the power supply requirements of current anti-corrosion.

[0197] In one embodiment of this application, the power supply module may be an air power supply module as disclosed in Embodiments 1 to 3 above, wherein the air power supply module is an air power supply module.

[0198] Furthermore, the water tank 4 is provided with an assembly part, and the air power supply module is disposed on the assembly part.

[0199] Specifically, in order to meet the installation requirements of the air-powered module, the water tank 4 is equipped with an assembly part to meet the installation and fixing requirements of the air-powered module.

[0201] In another embodiment of this application, for the electronic anode 5, it includes

[0202] Electrode rod 51;

[0203] Conductive rod 52, the electrode rod 51 is electrically connected to the conductive rod 52;

[0204] An insulating mounting base 53 is provided at its first end with a fixing connection portion 531, which is configured to seal the insulating mounting base 53 onto the inner liner 42.

[0206] The conductive rod 52 extends to the outside of the first end of the insulating mounting base 53, and the electrode rod 51 extends to the outside of the second end of the insulating mounting base 53, with the first end and the second end arranged opposite to each other;

[0207] A first sealing ring 54 is also fitted on the first end of the insulating mounting base 53. The first sealing ring 54 is configured to seal the connection between the guide rod and the first end of the insulating mounting base 53.

[0208] Specifically, the electronic anode 5 is fixedly mounted on the inner tank 42 via an insulating mounting base 53 during use. During use, because part of the insulating mounting base 53 extends into the inner tank 42, it will expand and contract due to temperature changes in the water within the inner tank 42.

[0209] Due to thermal expansion and contraction of the insulating mounting base 53, gaps will form between the insulating mounting base 53 and the electrode rod 51 and the conductive rod 52 after prolonged use, which will cause water in the inner liner 42 to leak from the electronic anode 5 through the gaps.

[0210] By adding a first sealing ring 54 at the connection between the first end of the insulating mounting base 53 and the conductive rod 52, the first sealing ring 54 effectively seals the connection between the insulating mounting base 53 and the conductive rod 52 from the outside. Thus, even if gaps are formed between the insulating mounting base 53 and the electrode rod 51 and the conductive rod 52, the water in the inner liner 42 flowing out through the gaps will be sealed and blocked by the first sealing ring 54 at the first end of the insulating mounting base 53, thereby effectively improving the sealing performance of the electronic anode 5.

[0211] In one embodiment, the conductive rod 52 extending to the outer end of the insulating mounting base 53 is further provided with a first threaded section 521, and a locking nut 55 is provided on the first threaded section 521.

After tightening the locking nut 55, the first sealing ring 54 will be pressed against the insulating mounting base 53 to achieve a good sealing effect.

[0215] Specifically, in order to facilitate the installation and positioning of the first sealing ring 54, an annular groove 532 can be provided on the end face of the first end of the insulating mounting base 53. During assembly, the first sealing ring 54 is placed into the annular groove 532, and then the locking nut 55 is tightened so that the first sealing ring 54 is squeezed into the annular groove 532.

[0216] In some embodiments, such as Figures 17-20 As shown, a washer 56 is also fitted on the first threaded section 521. The edge of the washer 56 is provided with a flange structure (not marked). The locking nut 55 presses the washer 56 against the end face of the first end of the insulating mounting base 53. The first sealing ring 54 is pressed between the end face of the first end of the insulating mounting base 53 and the washer 56. The flange structure is wrapped around the outside of the first sealing ring 54.

[0217] Specifically, in order to facilitate the installation and positioning of the first sealing ring 54, a washer 56 can be fitted on the outer end of the conductive rod 52. The washer 56 presses the first sealing ring 54 against the end face of the first end of the insulating mounting base 53, and the first sealing ring 54 is protected by the flange structure of the washer 56.

[0218] In another embodiment, to facilitate the power supply connection of the electronic anode 5, a terminal block 57 is provided on the outer end of the conductive rod 52 extending to the insulating mounting base 53.

[0219] Specifically, terminal 57 is mounted on conductive rod 52, and terminal 57 is electrically connected to power supply module via guide.

[0220] In some embodiments, the outer surface of the conductive rod 52 is provided with a plurality of annular ribs 522 arranged side by side, and the annular ribs 522 are located inside the insulating mounting base 53.

[0221] Specifically, the ring-shaped ribs can increase the contact area between the conductive rod 52 and the insulating mounting base 53, thereby increasing the flow path of water leakage when a gap occurs between them, which is more conducive to improving the reliability of use.

[0222] In other embodiments, the outer surface of the conductive rod 52 is provided with a plurality of annular grooves 523 arranged side by side, the annular grooves 523 being located within the insulating mounting base 53.

[0223] Specifically, the annular groove increases the contact area between the conductive rod 52 and the insulating mounting base 53, thereby increasing the flow path of water leakage when a gap occurs between them, which is more conducive to improving the reliability of use.

[0224] In another embodiment, a second sealing ring 58 is provided on the fixed connection portion 531, and the second sealing ring 58 is configured to seal the connection between the insulating mounting base 53 and the inner liner 42.
