[0033] Embodiment 1

[0034] like Figures 1 to 4As shown, the carbon dioxide gas enricher provided in this embodiment includes but is not limited to an upper bottle body 100, a lower bottle body 200, a connecting pipe 300, a bottle body up-and-down turning mechanism 400, an air supply pump 500 and a high-temperature filter 600, wherein the bottle mouth of the upper bottle body 100 and the bottle mouth of the lower bottle body 200 are arranged opposite to each other up and down and are connected to each other through the connecting pipe 300, and the interior of the lower bottle body 200 contains a carbon dioxide adsorbent solution; the bottle body up-and-down turning mechanism 400 is used to up-and-down turn the upper bottle body 100, the lower bottle body 200 and the connecting pipe 300. The output port of the air supply pump 500 is connected to the bottom of the inner cavity of the lower bottle body 200 so as to introduce the air outside the bottle into the carbon dioxide adsorbent solution, thereby causing the carbon dioxide gas in the air to react with the carbon dioxide adsorbent in the carbon dioxide adsorbent solution to form water-insoluble carbonate crystals; the high-temperature filter 600 is arranged inside the connecting pipe 300 so as to intercept the carbonate crystals when the bottle body assembly structure is turned upside down, and decompose the carbonate crystals at high temperature to obtain carbon dioxide gas and the carbon dioxide adsorbent that can fall down by itself.

[0035] like Figures 1 to 4 As shown, in the specific structure of the carbon dioxide gas enricher, the upper bottle body 100 and the lower bottle body 200 are a pair of bottles that can be interchanged by turning upside down, so as to contain the carbon dioxide adsorbent solution in time; Figures 1-2As shown, specifically, the upper bottle body 100 and / or the lower bottle body 200 may be, but not limited to, a conical bottle. The connecting pipe 300 is used to connect the upper bottle body 100 and the lower bottle body 200 so that the carbon dioxide adsorbent solution can flow from one bottle body to another bottle body during the upside-down turning process. In order to be able to guide out the air that has been adsorbed with carbon dioxide gas and the carbon dioxide gas obtained by high temperature decomposition, specifically, an air outlet 310 is opened on the side wall of the connecting pipe 300; and in order to further guide the air that has been adsorbed with carbon dioxide gas and the carbon dioxide gas obtained by high temperature decomposition to different flow directions at different time periods, the air outlet 310 can be connected to the air inlet port of a three-way valve, so that when the air outside the bottle is introduced into the carbon dioxide adsorbent solution, the air inlet port of the three-way valve is selected to be connected with the first air outlet port of the three-way valve to achieve the purpose of guiding out the air that has been adsorbed with carbon dioxide gas to the first flow direction, and when the carbonate crystals are decomposed at high temperature, the air inlet port of the three-way valve is selected to be connected with the second air outlet port of the three-way valve to achieve the purpose of guiding out the carbon dioxide gas obtained by high temperature decomposition to the second flow direction (for example, the flow direction leading to the mosquito killer); at the same time, in order to prevent the carbon dioxide adsorbent solution from leaking out through the air outlet 310 during the upside-down turning process, a gas separation membrane is preferably arranged in the air outlet 310. The air supply pump 500 can be implemented by using, but not limited to, an existing air pump. The high temperature in the high temperature filter 600 is a temperature that is relatively high compared to normal temperature and needs to reach the decomposition temperature of the carbonate crystals (for example, above 35 degrees Celsius). It generally needs to be heated after intercepting the carbonate crystals, that is, the high temperature filter 600 can be, but is not limited to, woven from electric heating wires / and non-electric heating wires (specifically, woven from electric heating wires, or woven from electric heating wires and non-electric heating wires), so that the high temperature can be obtained by heating the electric heating wires. In addition, the carbon dioxide adsorbent can specifically be, but is not limited to, guanidine or meta-phenylenediamine.

[0036] The working principle of the aforementioned carbon dioxide gas enricher may include, but is not limited to, the following: (1) introducing air outside the bottle into the carbon dioxide adsorbent solution through the air supply pump 500, so that the carbon dioxide gas in the air reacts with the carbon dioxide adsorbent in the carbon dioxide adsorbent solution to form water-insoluble carbonate crystals; (2) after a period of time, turning off the air supply pump 500, and flipping the bottle assembly structure upside down through the bottle body upside down mechanism 400, so that the upper bottle body 100 and the lower bottle body 200 are interchanged, and the carbon dioxide adsorbent solution flows into the new lower bottle body after the identity change (i.e., the upper bottle body 100 before the identity change) after passing through the high-temperature filter 600. At this time, due to the The high temperature filter 600 intercepts the carbonate crystals; (3) the carbonate crystals are decomposed by the high temperature filter 600 to obtain carbon dioxide gas and carbon dioxide adsorbent that can fall down by itself (i.e., the carbon dioxide adsorbent solution that falls down and dissolves to obtain a carbon dioxide adsorbent solution with a higher concentration). Although there is air in the bottle at this time, the carbon dioxide gas obtained by decomposition is adsorbed from a large amount of air outside the bottle. Therefore, after the carbon dioxide gas obtained by decomposition is mixed with the air in the bottle, the purpose of carbon dioxide gas enrichment can still be achieved (note that the purpose of carbon dioxide gas purification is not achieved here); (4) the air outside the bottle is introduced into the carbon dioxide adsorbent solution through the air supply pump 500 again to start the next cycle. Therefore, the aforementioned carbon dioxide gas enricher provided by this embodiment can greatly simplify the air separation system and reduce the system volume while achieving the purpose of carbon dioxide gas enrichment, so that it can be applied to small equipment such as mosquito killing devices that use the tendency of mosquitoes to carbon dioxide gas to lure and kill mosquitoes, which is convenient for practical application and promotion.
