Description

Technical Field

[0001] The invention belongs to a gas production device, and in particular relates to an integrated carbon dioxide production device. Background Art

[0002] In the field of aquaculture, especially in fish tanks and grass tanks, carbon dioxide plays a vital role in the growth of aquatic plants. Adequate supply of carbon dioxide can promote the photosynthesis of aquatic plants, allowing them to thrive, thereby maintaining the balance and beauty of the aquatic ecosystem.

[0003] At present, there are many carbon dioxide gasification devices for fish tanks or grass tanks on the market. However, these existing devices generally have some problems that need to be solved. Among them, poor maintenance convenience is a more prominent problem. When performing maintenance operations on existing devices, it is often necessary to perform more complicated disassembly and assembly steps on the device, and the reaction liquid is mixed and added to the container at one time, and the reaction speed cannot be controlled.

[0004] This not only takes time and effort, but more importantly, during the maintenance process, the exhaust end is easily affected due to the unreasonable design of the device structure. Once the exhaust end is affected, the exhaust pipe is very likely to fall off from the aquarium, which will cause the prepared carbon dioxide to be unable to be smoothly transported to the aquarium, making it impossible for aquatic plants to obtain sufficient carbon dioxide supply, seriously affecting the normal growth of aquatic plants, and further destroying the stability of the entire aquarium ecosystem.

[0005] In summary, the existing carbon dioxide gasification devices used in fish tanks or plant tanks have obvious defects in maintenance convenience and stability of use. There is an urgent need for a new type of carbon dioxide gasification device to solve these problems in order to meet the needs of aquarium farming enthusiasts for a stable and efficient carbon dioxide supply system. Summary of the invention

[0006] In view of the defects in the prior art, the present invention provides an integrated carbon dioxide generating device with simple structure and convenient maintenance.

[0007] The integrated carbon dioxide generating device provided by the present invention comprises: a cup cover, an upper cup body and a lower cup body, which are connected in sequence from top to bottom, wherein the upper cup body is used to place a first reaction liquid, and the lower cup body is used to place 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 air 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, and is used to draw the first reaction liquid in the upper cup body into the lower cup body, reacting with the second reaction liquid to generate carbon dioxide; the cup cover is provided with an exhaust hole.

[0008] The working principle of the integrated carbon dioxide generating device provided by the present invention is as follows: before use, a first reaction liquid is placed in the upper cup body, and a second reaction liquid is placed in the lower cup body. After the water pump is started, the first reaction liquid and the second reaction liquid are mixed and reacted in the lower cup body to generate carbon dioxide. Since the upper cup body and the lower cup body are connected through air holes, the carbon dioxide in the lower cup body can enter the upper cup body and be discharged through the drain hole of the cup cover.

[0009] The integrated carbon dioxide generating device of the present invention is mainly used to provide carbon dioxide to the grass tank. The cup cover, 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 extended into and fixed in the grass tank. After a period of use, the waste liquid needs to be poured out and reacted in the lower cup body, so that the upper cup body does not need to be moved when pouring the waste liquid, which can prevent the upper cup body from pulling the exhaust pipe and causing the exhaust pipe to fall off the grass tank.

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

[0011] According to an embodiment of the present invention, the cup cover is provided with control keys and a display screen.

[0012] According to an embodiment of the present invention, the cup cover is further provided with an air pressure sensor for detecting the air pressure in the upper cup body. The air pressure sensor is provided with a shell outside, and the shell is provided with air holes, and the air holes are provided with a waterproof breathable membrane.

[0013] According to an embodiment provided by the present invention, when the air pressure in the upper cup body is lower than the low point threshold, the water pump works to draw the reaction liquid in the upper cup body into the lower cup body; when the air pressure in the upper cup body is higher than the high point threshold, the water pump stops working.

[0014] According to an embodiment of the present invention, the liquid hole further extends downward to the interior of the lower cup body through a lower water pipe.

[0015] According to an embodiment of the present invention, the exhaust hole is connected to a bubble refiner via an exhaust pipe, and the exhaust pipe is provided with a check valve.

[0016] According to an embodiment of the present invention, a sealing ring is provided between the cup cover and the upper cup body, and between the upper cup body and the lower cup body.

[0017] According to an embodiment of the present invention, the cup cover is provided with a charging stand, and the main control board is powered by a battery or an external power supply.

[0018] According to an embodiment of the present invention, the reaction liquid in the upper cup body is citric acid, and the reaction liquid in the lower cup body is baking soda. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0025] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0026] Reference Figure 1 and Figure 2 The integrated carbon dioxide generating device of this embodiment includes a cup cover 7, an upper cup body 15 and a lower cup body 18 connected in sequence from top to bottom. The upper cup body 15 is used to place the first reaction liquid, and the lower cup body 18 is used to place the second reaction liquid. The upper cup body 15 and the lower cup body 18 are connected through air holes and liquid holes, and the air holes are 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 in the upper cup body 15, and the water pump 16 is connected to the liquid hole, which is used to draw the first reaction liquid in the upper cup body 15 into the lower cup body 18 to react with the second reaction liquid to generate carbon dioxide. The cup cover 7 is provided with an exhaust hole 20 for discharging the generated carbon dioxide.

[0027] Before use, a first reaction liquid (such as a citric acid solution) is placed in the upper cup body 15, and a second reaction liquid (such as a baking soda solution) is placed in the lower cup body 18. After starting the water pump 16, the first reaction liquid is pumped into the lower cup body 18, and mixed with the second reaction liquid to generate carbon dioxide. Since the upper cup body 15 and the lower cup body 18 are connected through the pores, the carbon dioxide generated in the lower cup body 18 can enter the upper cup body 15 and be discharged through the exhaust hole 20 of the cup cover 7. The exhaust hole 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.

[0028] An air pressure sensor 10 is provided inside the cup cover 7 to detect the air pressure inside the upper cup body 15. An outer shell 8 is provided outside the air pressure sensor 10, and an air hole is provided on the outer shell 8. The air hole is covered with a waterproof breathable membrane 9 to prevent water vapor from entering the outer shell 8. A protective cover 11 is also provided below the outer shell 8 to isolate the reaction liquid and prevent the reaction liquid from splashing onto the waterproof breathable membrane 9 and affecting the air permeability. When the air pressure inside the upper cup body 15 is lower than the set low point threshold, the water pump 16 starts to pump the first reaction liquid into the lower cup body 18; when the air pressure is higher than the set high point threshold, the water pump 16 stops working to ensure that the air pressure is maintained within the set range.

[0029] The cup cover 7 is provided with control keys and a display screen 4, wherein the control keys include a start key (such as a touch key 3), and the display screen 4 is a digital tube for displaying the working state of the device. An electrical compartment is also provided inside the cup cover 7, wherein a main control board 6 is provided inside the electrical compartment, and the main control board 6 is powered by a battery or an external power supply. The electrical compartment is provided with a top cover 2, and a lens 1 is provided outside the top cover 2 for convenient observation of the internal state.

[0030] The water pump 16 can be arranged in the upper cup body 15 or on the cup cover 7. The outlet of the water pump 16 is connected to the liquid hole through the water outlet elbow 13 and the silicone tube 14. The liquid hole extends downward to the inside of the lower cup body 18 through the downpipe 17, reducing the height of the outlet of the downpipe 17, thereby reducing the working noise.

[0031] Sealing rings 12 are provided between the cup cover 7 and the upper cup body 15 and between the upper cup body 15 and the lower cup body 18 to ensure the sealing of the device. The circuit structure in the electrical compartment is centrally arranged, and only the electrical compartment needs to be waterproofed, which has a simple structure and is easy to maintain.

[0032] The specific implementation steps are as follows:

[0033] Prepare the reaction liquid: put citric acid and add water into the upper cup body 15 to form a first reaction liquid; put baking soda and add a small amount of water into the lower cup body 18 to form a second reaction liquid.

[0034] Starting device: Press the start button on the cup cover 7, the water pump 16 starts to work, pumping the citric acid solution into the lower cup body 18, and reacting with baking soda to generate carbon dioxide.

[0035] Gas generation and discharge: The generated carbon dioxide enters the upper cup body 15 through the air holes, and after reaching a certain pressure, it is discharged through the exhaust holes 20 and the bubble refiner 21 to form refined carbon dioxide gas.

[0036] Automatic control: When the air pressure in the upper cup body 15 is lower than the low point threshold, the water pump 16 starts; when the air pressure is higher than the high point threshold, the water pump 16 stops, ensuring continuous generation of gas.

[0037] The integrated carbon dioxide generating device of this embodiment has the advantages of simple structure, convenient maintenance, and convenient use. The cup cover 7, the upper cup body 15, and the lower cup body 18 are connected in sequence, occupying a small space, and are easy to install and use. The circuit structure is centralized in the electrical compartment, and only the electrical compartment needs to be waterproofed, which is simple to maintain. When pouring waste liquid, there is no need to move the upper cup body 15 to prevent the exhaust pipe from falling off the grass tank, making the operation more convenient.
