Description

Technical Field

[0001] This utility model pertains to gas production devices, and specifically relates to an integrated carbon dioxide generating device. Background Technology

[0002] In aquariums, especially in fish tanks and planted aquariums, carbon dioxide plays a crucial role in the growth of aquatic plants. An adequate supply of carbon dioxide promotes photosynthesis, allowing aquatic plants to thrive and thus maintaining the balance and aesthetics of the aquarium ecosystem.

[0003] Currently, there are various carbon dioxide generators available on the market for aquariums or planted tanks. However, these existing devices generally suffer from several problems that urgently need to be addressed. One particularly prominent issue is poor maintenance convenience. Maintenance of existing devices often requires complex disassembly and assembly procedures, and the reaction solution is mixed and added to the container all at once, making it impossible to control the reaction rate.

[0004] This not only consumes time and effort, but more importantly, during maintenance, the poorly designed structure of the device makes it easy to disturb the exhaust end. Once the exhaust end is disturbed, the exhaust pipe can easily detach from the aquarium, preventing the prepared carbon dioxide from being properly delivered to the aquarium. This results in insufficient carbon dioxide supply to the aquatic plants, severely affecting their normal growth and ultimately disrupting the stability of the entire aquarium ecosystem.

[0005] In conclusion, existing carbon dioxide generators for aquariums or planted tanks have significant shortcomings in terms of ease of maintenance and operational stability. There is an urgent need for a new type of carbon dioxide generator to solve these problems and meet the needs of aquarium enthusiasts for a stable and efficient carbon dioxide supply system. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides an integrated carbon dioxide generating device with simple structure and convenient maintenance.

[0007] The integrated carbon dioxide generating device provided by this utility model includes, from top to bottom, a cup lid, an upper cup body, and a lower cup body connected in sequence. The upper cup body is used to hold a first reaction liquid, and the lower cup body is used to hold a second reaction liquid. An air hole and a liquid hole are connected between the upper cup body and the lower cup body. The air hole is used to maintain the gas pressure balance in the upper cup body and the lower cup body. A water pump is provided in the upper cup body, and the water pump is connected to the liquid hole to pump the first reaction liquid in the upper cup body into the lower cup body to react with the second reaction liquid and generate carbon dioxide. The cup lid is provided with an exhaust hole.

[0008] The working principle of the integrated carbon dioxide generating device provided by this utility model is as follows: Before use, a first reaction liquid is placed in the upper cup and a second reaction liquid is placed in the lower cup. After the water pump is started, the first reaction liquid and the second reaction liquid are mixed and reacted in the lower cup to generate carbon dioxide. Since the upper cup and the lower cup are connected by a vent, the carbon dioxide in the lower cup can enter the upper cup and be discharged through the vent hole of the cup lid.

[0009] This utility model's integrated carbon dioxide generator is mainly used to provide carbon dioxide to a planted aquarium. The cup lid, upper cup body, and lower cup body are connected in sequence, with a simple structure and small space occupation. On the other hand, when in use, the end of the exhaust pipe needs to be inserted into and fixed inside the planted aquarium. After a period of use, the waste liquid needs to be poured out and reacted in the lower cup body. This means that the upper cup body does not need to be moved when pouring out the waste liquid, which can prevent the upper cup body from pulling the exhaust pipe and causing the exhaust pipe to fall off the planted aquarium.

[0010] According to one embodiment of the present invention, the cup lid is provided with an electrical compartment, and the electrical compartment is provided with a main control board.

[0011] According to one embodiment of the present invention, the cup lid is provided with control buttons and a display screen.

[0013] According to one embodiment of the present invention, the air pressure sensor is provided with a housing, and the housing is provided with a vent hole, and the vent hole is provided with a waterproof and breathable membrane.

[0014] According to one embodiment of this utility model, when the air pressure in the upper cup is less than the low point threshold, the water pump works to draw the reaction liquid in the upper cup into the lower cup; when the air pressure in the upper cup is greater than the high point threshold, the water pump stops working.

[0015] According to one embodiment of the present invention, the liquid hole also extends downward into the interior of the lower cup body through a drain pipe.

[0016] According to one embodiment of the present invention, the exhaust port is connected to a bubble refiner via an exhaust pipe, and the exhaust pipe is equipped with a check valve.

[0017] According to one embodiment of the present invention, a sealing ring is provided between the cup lid and the upper cup body, and between the upper cup body and the lower cup body.

[0018] According to one embodiment of the present invention, the cup lid is provided with a charging base, and the main control board is powered by a battery or an external power source.

[0019] According to one embodiment of the present invention, the reaction liquid in the upper cup is citric acid, and the reaction liquid in the lower cup is baking soda. Attached Figure Description

Detailed Implementation

[0025] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0026] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0027] Reference Figure 1 and Figure 2The integrated carbon dioxide generating device of this embodiment includes a lid 7, an upper cup body 15, and a lower cup body 18 connected sequentially from top to bottom. The upper cup body 15 is used to hold a first reaction liquid, and the lower cup body 18 is used to hold a second reaction liquid. The upper cup body 15 and the lower cup body 18 are connected by an air hole and a liquid hole, the air hole being used to maintain the air pressure balance between the upper cup body 15 and the lower cup body 18. A water pump 16 is provided inside the upper cup body 15, and the water pump 16 is connected to the liquid hole, used to pump the first reaction liquid in the upper cup body 15 into the lower cup body 18, where it reacts with the second reaction liquid to generate carbon dioxide. The lid 7 is provided with an exhaust port 20 for discharging the generated carbon dioxide.

[0028] Before use, place a first reaction solution (such as citric acid solution) in the upper cup 15 and a second reaction solution (such as baking soda solution) in the lower cup 18. After starting the water pump 16, the first reaction solution is drawn into the lower cup 18 and mixes with the second reaction solution to generate carbon dioxide. Since the upper cup 15 and the lower cup 18 are connected by an air vent, the carbon dioxide generated in the lower cup 18 can enter the upper cup 15 and be discharged through the vent 20 of the cup lid 7. The vent 20 is connected to a bubble refiner 21 through an exhaust pipe, and a check valve 19 is provided on the exhaust pipe to prevent gas backflow.

[0029] A pressure sensor 10 is installed inside the lid 7 to detect the air pressure inside the upper cup body 15. The pressure sensor 10 is surrounded by a housing 8 with vent holes covered by a waterproof and breathable membrane 9 to prevent moisture from entering. A protective cover 11 is also installed below the housing 8 to isolate the reaction liquid and prevent it from splashing onto the waterproof and breathable membrane 9, thus affecting air permeability. When the air pressure inside the upper cup body 15 is lower than a set low threshold, the water pump 16 starts, drawing the first reaction liquid into the lower cup body 18; when the air pressure is higher than a set high threshold, the water pump 16 stops working, ensuring the air pressure is maintained within the set range.

[0030] The cup lid 7 is equipped with control buttons and a display screen 4. The control buttons include a start button (such as a touch button 3), and the display screen 4 is a digital tube used to display the working status of the device. The cup lid 7 also houses an electrical compartment containing a main control board 6, which is powered by a battery or an external power source. The electrical compartment has a top cover 2, and a lens 1 is mounted on the outside of the top cover 2 for easy observation of the internal status.

[0031] The water pump 16 can be installed inside the upper cup body 15 or on the cup lid 7. The outlet of the water pump 16 is connected to the liquid hole through the water outlet bend 13 and the silicone tube 14. The liquid hole extends downward into the lower cup body 18 through the drain pipe 17, reducing the height of the drain pipe 17 outlet and thus reducing operating noise.

[0032] Sealing rings 12 are provided between the cup lid 7 and the upper cup body 15, and between the upper cup body 15 and the lower cup body 18, to ensure the airtightness of the device. The circuit structure inside the electrical compartment is centrally located, requiring only waterproofing of the electrical compartment, making the structure simple and easy to maintain.

[0033] The specific implementation steps are as follows:

[0034] Prepare the reaction solution: Add citric acid and water to the upper cup 15 to form the first reaction solution; add baking soda and a small amount of water to the lower cup 18 to form the second reaction solution.

[0035] Activation device: Press the start button on the cup lid 7, and the water pump 16 will start working, drawing the citric acid solution into the lower cup body 18, where it reacts with baking soda to produce carbon dioxide.

[0036] Gas generation and discharge: The generated carbon dioxide enters the upper cup 15 through the vent, and after reaching a certain pressure, it is discharged through the exhaust port 20 and the bubble refiner 21, forming refined carbon dioxide gas.

[0037] Automatic control: When the air pressure inside the upper cup 15 is lower than the low threshold, the water pump 16 starts; when the air pressure is higher than the high threshold, the water pump 16 stops, ensuring continuous gas production.

[0038] The integrated carbon dioxide generator of this embodiment has the advantages of simple structure, convenient maintenance, and easy use. The cup lid 7, upper cup body 15, and lower cup body 18 are connected in sequence, occupying little space and facilitating installation and use. The centralized circuit structure inside the electrical compartment only requires waterproofing the electrical compartment, simplifying maintenance. When emptying waste liquid, there is no need to move the upper cup body 15, preventing the exhaust pipe from falling off the aquarium, making operation even more convenient.

[0039] It should be noted that the functions, algorithms, and methods involved in this utility model are merely conventional adaptive applications of existing technologies. Therefore, the improvement of existing technologies by this utility model lies essentially in the connection relationship between hardware components, rather than in the functions, algorithms, and methods themselves.
