[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Example 1 like Figures 1-12 This utility model provides a carbon dioxide absorption device 120 that is easy to assemble and disassemble, comprising: a shell 200, an inner core 500, a connecting component 300, and an elastic component 400. The shell 200 has a first cavity inside, and first through holes are provided at both ends of the shell 200.

[0022] The inner core 500 is detachably installed in the first cavity. The inner core 500 has a second cavity inside, which is filled with a gas filter component 510. In this embodiment, the gas filter component 510 is a carbon dioxide absorbent or a carbon dioxide filter layer, etc. The effective component inside can be an alkaline oxide, such as calcium hydroxide. However, if calcium hydroxide is used, an additional water-absorbing layer is required to absorb the water generated by the reaction of calcium hydroxide and carbon dioxide. The inner core 500 has docking parts at both ends, which are connected to the second cavity.

[0023] The outer shell 200 and the inner core 500 can be made of transparent materials, such as acrylic. A color indicator can be added to the gas filter component 510. When the alkaline reagent in the gas filter component 510 has reacted completely, the color of the indicator changes. The color change of the gas filter component 510 can be observed from the outside, thereby determining when to replace the inner core 500.

[0024] A connecting component 300 is disposed at at least one end of the outer casing 200 and is movably connected to the first through hole. One end of the connecting component 300 is used to connect to the air pipe 110, and the other end is used to connect to the mating portion of the inner core 500. An elastic component 400 is connected to the connecting component 300 and the outer casing 200, and the elastic component 400 is used to drive the connecting component 300 to move closer to the inner core 500. In this embodiment, connecting components 300 are provided at both ends of the outer casing 200.

[0025] The connecting component 300 has a gas channel 310. The connecting component 300 is a hollow cylindrical structure that allows gas flow. One end of the connecting air tube 110 has an anti-detachment protrusion 320, and the other end has a chamfer. The anti-detachment protrusion 320 is annularly arranged on the surface of the connecting component 300, and its cross-section is barbed. When the air tube 110 is connected to the connecting component 300, the anti-detachment protrusion 320 prevents the air tube 110 from falling off. Multiple anti-detachment protrusions 320 can be provided. The chamfer guides the connecting component 300 into the mating hole 520 of the inner core 500.

[0026] A limiting part 330 is provided on the connecting component 300, and the limiting part 330 is located inside the first cavity. One end of the elastic component 400 is connected to the limiting part 330, and the other end is connected to the inner wall of the first cavity. In this embodiment, the limiting part 330 is a limiting block, which is located on the connecting component 300 relatively close to the inner core 500. The elastic component 400 is a spring, which is sleeved on the outside of the connecting component 300. One end of the spring abuts against the limiting part 330, and the other end abuts against the inner wall of the first cavity. During use, the connecting component 300 is pushed into the inner core 500 by the elastic force of the spring.

[0027] like Figures 7-8The mating part includes mating holes 520 and sealing components 521. The mating holes 520 are located at both ends of the inner core 500 and connect to the gas filter component 510. Several sealing components 521 are disposed within the mating holes 520, and each sealing component 521 has a second through hole through which the connecting component 300 passes. In this embodiment, the mating holes 520 have chamfered edges to guide the connecting component 300 into the mating holes 520. The sealing components 521 are sealing rings. Two annular grooves for installing the sealing rings are formed within the mating holes 520. When the connecting component 300 is inserted into the mating holes 520, the inner ring of the sealing ring tightly fits onto the surface of the connecting component 300, achieving an airtight seal.

[0028] The gas flow path is as follows: the gas enters the gas channel 310 of the connecting component 300 through the gas tube 110, and then enters the inner core 500 from the docking part. The gas that has absorbed carbon dioxide enters the connecting component 300 from the docking part, then enters the gas tube 110 from the connecting component 300, and finally enters the reagent bottle 100.

[0029] The first cavity is provided with a bracket 201 for supporting the inner core 500. The bracket 201 is strip-shaped and multiple brackets are provided in the first cavity. The bracket 201 can be used to position the inner core 500 so that the connecting part 300 is aligned with the mating hole 520. At the same time, it can reduce the friction between the inner core 500 and the inner wall of the first cavity.

[0030] The outer casing 200 includes a first outer casing 210 and a second outer casing 220, which are detachably connected. In this embodiment, both the first outer casing 210 and the second outer casing 220 are cylindrical, and they are detachably connected by snap fasteners 230. Multiple snap fasteners 230 are provided along the periphery of the outer casing 200, thereby improving the reliability of the connection between the first outer casing 210 and the second outer casing 220. The snap fastener connection is simple and convenient to install and remove, enabling quick replacement of the inner core 500. Figure 12 In other embodiments, the outer shell 200 may also take the shape of a triangular prism, a square prism, a pentagonal prism, a hexagonal prism, etc.

[0031] Example 2 like Figures 9-10The main difference between this embodiment and Embodiment 1 is that: the first outer shell 210 is provided with multiple locking blocks 211, and the second outer shell 220 is provided with multiple locking slots 221. The locking blocks 211 and the locking slots 221 correspond one-to-one, and the locking slots 221 are L-shaped. When connecting the first outer shell 210 and the second outer shell 220, the locking blocks 211 are aligned with the locking slots 221, and then the first outer shell 210 and the second outer shell 220 are pressed together. Parts of the first outer shell 210 and the second outer shell 220 overlap, or in other words, the second outer shell 220 covers a part of the first outer shell 210, so that the locking blocks 211 can be inserted into the horizontal part of the locking slots 221. Then, the first outer shell 210 and the second outer shell 220 are rotated so that the locking blocks 211 are inserted into the vertical part of the locking slots 221, thereby preventing the first outer shell 210 and the second outer shell 220 from becoming loose.

[0032] Example 3 The main difference between this embodiment and embodiment one is that a connecting component 300 is movably connected in a first through hole of the outer shell 200. When the outer shell 200 is provided with a connecting component 300 on only one side, the connecting component 300 is connected to the gas pipe 110, and the gas pipe 110 is connected to the reagent bottle 100. In this way, external gas can enter the inner core 500 through the gas filter component 510 and be filtered.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
