Description

Technical Field

[0001] This application relates to the field of hydrogen engine technology, specifically to a hydrogen engine. Background Technology

[0002] A hydrogen generator typically refers to a device or machine that can produce hydrogen. It can convert other substances into hydrogen through different principles and technologies. Hydrogen generators are generally divided into water electrolysis hydrogen generators, chemical hydrogen generators, and biological hydrogen generators. For home hydrogen generators, water electrolysis is often used to produce hydrogen, which is then used in health and wellness processes such as relieving oxidative stress, anti-fatigue, and improving immunity.

[0003] Existing home hydrogen generators can electrolyze pure water to produce hydrogen and oxygen, which is convenient to use. However, in order to increase the conductivity of water, it is often necessary to heat the pure water. Existing hydrogen generators lack a temperature control structure to prevent the pure water from being overheated. This can lead to the risk of the electrolytic cell burning out due to overheating of the pure water or abnormal heating of the machine body. Utility Model Content

[0004] The main objective of this application is to provide a hydrogen generator that addresses the technical problem in the prior art where the lack of protection against overheating of pure water leads to high-temperature damage to the electrolytic cell.

[0005] The technical solution adopted in this application is as follows:

[0006] A hydrogen generator includes a chassis, inside which are arranged an electrolytic cell and a water tank. The electrolytic cell is located below the water tank, and the water tank is provided with a water supply pipe connected to the electrolytic cell. A first liquid level sensor for monitoring low water levels is installed inside the water tank. An audible and visual alarm is installed outside the chassis. A semiconductor cooling chip is fixedly connected to the outer wall of the electrolytic cell, and heat dissipation fins are fixedly connected to the back of the semiconductor cooling chip. A cooling fan is fixedly installed on the chassis wall, and the cooling fan is positioned opposite to the heat dissipation fins. A temperature sensor and a second liquid level sensor for monitoring low liquid levels are installed inside the electrolytic cell.

[0007] Optionally, the electrolytic cell is provided with two electrolytic electrode plates, and the upper surface of the electrolytic cell is fixedly connected to two exhaust pipes corresponding to the anode and cathode of the electrolytic electrode plates.

[0008] Optionally, the water tank includes a tank body and a tank cover, the tank cover is provided with a water injection pipe, and a plunger is provided inside the water injection pipe.

[0009] Optionally, the water injection pipe includes a pipe body and a hexagonal cap integrally formed with the pipe body, the water tank cover is provided with a threaded hole, and the pipe body is threadedly installed in the threaded hole.

[0010] Optionally, the water injection pipe is connected to a filter cylinder, and the filter cylinder is detachably connected to the water injection pipe.

[0011] Optionally, the filter cartridge includes a connecting cylinder portion and a filter cartridge portion, wherein the connecting cylinder portion is provided with a stepped portion inserted into the water injection pipe, and the stepped portion is connected to the water injection pipe by bolts.

[0012] Optionally, the chassis includes a chassis body and a chassis cover, and the chassis cover is provided with a through hole for the hexagonal nut and the temperature sensor to extend out.

[0013] Optionally, the chassis cover is fixed to the chassis body by bolts.

[0015] Optionally, a controller is provided on the outer wall of the water tank, and the controller is connected to the semiconductor cooling chip, the cooling fan, the temperature sensor, the first liquid level sensor, the second liquid level sensor, and the audible and visual alarm.

[0016] Compared with the prior art, the beneficial effects of this application are:

[0017] This application discloses a hydrogen generator, including a chassis. An electrolytic cell and a water tank are disposed inside the chassis. The electrolytic cell is located below the water tank, and the water tank is connected to the electrolytic cell via a water supply pipe. A first liquid level sensor for monitoring low water levels is disposed inside the water tank. A semiconductor cooling chip is fixedly connected to the outer wall of the electrolytic cell, and heat dissipation fins are fixedly connected to the back of the semiconductor cooling chip. A cooling fan is fixedly disposed on the chassis wall, and the cooling fan is positioned opposite the heat dissipation fins. A temperature sensor and a second liquid level sensor for monitoring low liquid levels are disposed inside the electrolytic cell. By placing the water tank above the electrolytic cell and connecting it via the water supply pipe, the second liquid level sensor can be used to open the water supply pipe. Water is added to the electrolytic cell. A first liquid level sensor inside the water tank detects low water levels and issues an early warning to prevent the electrolytic cell from drying out. Simultaneously, a temperature sensor monitors the temperature inside the electrolytic cell. When the temperature exceeds the limit, the semiconductor cooling chip is energized and comes into contact with the electrolytic cell to cool it, neutralizing the heat inside. Heat dissipation fins promptly dissipate heat from the back of the semiconductor cooling chip, and a cooling fan accelerates the heat dissipation through the heat dissipation fins. This effectively prevents the pure water in the electrolytic water tank from being overheated and burning out the electrolytic plates. It also avoids the risk of hydrogen explosion due to high temperature instability caused by the lack of a temperature control structure to prevent the pure water from being overheated inside the machine or abnormal heat generation in the machine.

[0029] See attached document Figure 1 This application provides a hydrogen generator, including a chassis 1. The chassis 1 consists of a chassis body 101 and a chassis cover 102. The chassis cover 102 is assembled and connected to the chassis body 101 by bolts located near the four corners. The chassis cover 102 can be removed by removing the bolts to repair and maintain the components inside the chassis body 101.

[0030] like Figure 2 and Figure 3As shown, the casing 1 contains an electrolytic cell 2 and a water tank 3. The electrolytic cell 2 is fixed to the inner bottom surface of the casing 101. A temperature sensor 4 and a second liquid level sensor 6 for monitoring low water levels are fixedly installed on the inner wall of the electrolytic cell 2. The signal lines of the temperature sensor 4 and the second liquid level sensor 6 extend upward from the top of the electrolytic cell 2 outside the casing 1, and the gap between the signal lines and the electrolytic cell 2 is sealed with sealant. Two electrolytic electrode plates are installed inside the electrolytic cell 2. The two electrolytic electrode plates generate hydrogen on the cathode side and oxygen on the anode side, respectively. Two exhaust pipes 8 are fixedly connected to the upper surface of the electrolytic cell 2 corresponding to the anode and cathode of the electrolytic electrode plates. The water tank 3 is fixed above the electrolytic cell 2, and the water tank 3 is provided with a water supply pipe 9 that connects to the inside of the electrolytic cell 2. A solenoid valve is installed on the water supply pipe 9. A first liquid level sensor 5 for monitoring low water levels is installed inside the water tank 3. An audible and visual alarm 11 is installed outside the casing 1. When the second liquid level sensor 6 detects a low liquid level in the electrolytic cell 2, the solenoid valve will be opened to inject water into the electrolytic cell 2. When the first liquid level sensor 5 detects a low water level in the water tank 3, it will issue an early alarm. At this time, the electrolytic cell 2 is still filled with water, thus allowing sufficient time to replenish the electrolytic water even if the liquid level alarm is not detected in time, preventing the electrolytic cell 2 from drying out.

[0031] At the same time, such as Figures 2 to 4 As shown, a thermoelectric cooler 14 is fixedly connected to the outer wall of the electrolytic cell 2. A heat dissipation fin is fixedly connected to the back of the thermoelectric cooler 14. The side of the thermoelectric cooler 14 that is in contact with the electrolytic cell 2 is the cooling side, which helps to neutralize the excess heat in the electrolytic cell 2. The side of the thermoelectric cooler 14 that is in contact with the heat dissipation fin 15 is the heating side, which removes heat through the heat dissipation fin. The chassis 101 has heat dissipation holes on its walls. A cooling fan 16 is fixedly installed in the heat dissipation holes, which removes the heat from the heat dissipation fin 15.

[0032] like Figure 1 As shown, a controller 10 is installed on the outer wall of the chassis 1. A semiconductor cooling chip 14, a cooling fan 16, a temperature sensor 4, two electrolytic electrode plates, a component for heating the electrolytic cell 2, a first liquid level sensor 5, a second liquid level sensor 6, and an audible and visual alarm 11 are all electrically connected to the controller 10 via signal lines.

[0033] As can be imagined, the hydrogen generator provided in this application embodiment, by placing a water tank 3 on top of the electrolytic cell 2 and connecting it via a water supply pipe 9, achieves automatic water injection without the need for an additional water pump structure, saving costs. A second liquid level sensor 6 monitors the water level in the electrolytic cell 2. When the electrolytic cell 2 is at a low water level, the controller 10 controls the solenoid valve to open, allowing water to be injected into the electrolytic cell 2 via the water supply pipe 9. A first liquid level sensor 5 installed in the water tank 3 detects the water level in the tank 3. When the water tank 3 is at a low water level, an alarm is triggered, indicating that the electrolytic cell 2 is in a water-containing state, thus providing an early warning and preventing the electrolytic cell 2 from dry-burning. Simultaneously, a temperature sensor... Device 4 monitors the temperature inside the electrolytic cell 2. When the temperature exceeds the limit, the semiconductor cooling chip 14 is powered on by the controller 10, which then contacts the electrolytic cell 2 to cool it and neutralize the heat inside the electrolytic cell 2. The heat dissipation fins promptly dissipate the heat from the back of the semiconductor cooling chip 14. At the same time, the heat dissipation fan 16 is powered on to accelerate the heat dissipation from the heat dissipation fins, effectively preventing the pure water in the electrolytic water tank 3 from being overheated and causing the electrolytic plate 7 to burn out. This avoids the problem of hydrogen gas being unstable at high temperatures and causing an explosion due to the lack of a temperature control structure to prevent the pure water from being overheated in the machine or the machine body becoming abnormally hot.

[0034] In a preferred embodiment, such as Figures 2 to 5 As shown, the water tank 3 includes a water tank body 301 and a water tank cover 302. A water injection pipe 12 is provided on the water tank cover 302, and a plunger 17 is provided inside the water injection pipe 12. The chassis cover 102 is provided with a through hole, and the water injection pipe 12 extends upward from the chassis 1 through the through hole. Water can be injected into the water tank 3 through the water injection pipe 12 by removing the plunger 17.

[0035] In the above, such as Figures 2 to 5 As shown, a filter cylinder 13 is installed on the water injection pipe 12. The filter cylinder 13 uses a resin filter element to filter impurities in the water and reduce the total amount of dissolved solids in the water.

[0036] Of course, in order to facilitate the replacement of the filter cartridge 13, in a preferred embodiment, the water injection pipe 12 includes a pipe body 1201 and a hexagonal cap 1202 integrally formed with the pipe body 1201. The pipe body 1201 is provided with external threads, and the water tank cover 302 has a threaded hole. The pipe body 1201 is installed on the water tank cover 302 by means of threaded connection. The hexagonal cap 1202 extends out from the housing cover 102, and the hexagonal cap 1202 can be used with a hexagonal wrench to remove the water injection pipe 12 from the water tank cover 302, thereby removing the filter cartridge 13. The filter cartridge 13 includes a connecting cylinder portion 1301 and a filter cartridge portion 1302. The connecting cylinder portion 1301 is provided with a stepped portion that is inserted into the water injection pipe 12. The stepped portion and the pipe body 1201 are provided with bolt holes in the radial direction. Bolts that fix the stepped portion and the pipe body 1201 are provided in the bolt holes. Thus, after the filter cartridge 13 is removed, the bolts connecting the stepped portion and the pipe body 1201 can be removed to replace the filter cartridge 13.

[0037] It can be seen that the hydrogen generator provided in this application embodiment filters impurities in the water by connecting and installing a filter cartridge 13 at the water injection pipe 12, thereby reducing the total amount of dissolved solids in the water. The water injection pipe 12 is threadedly connected to the water tank cover 302, and the filter cartridge 13 is bolted to the water injection pipe 12, which facilitates the disassembly and assembly of the filter cartridge 13 and provides convenience for the replacement of the filter cartridge 13.

[0038] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
