Carbon dioxide absorption ball

The utility model relates to the technical field of solid carbon dioxide absorption, in particular to a carbon dioxide absorption ball. The carbon dioxide absorption ball is characterized by comprising a ball body, a concave hole is formed in the outer surface of the ball body, an indicator layer is arranged on the outer side of the ball body, a hollow body is arranged in the ball body, and a communication channel is arranged between the hollow body and the concave hole. The sunken holes are used for increasing the surface area of the sphere and improving the carbon dioxide absorptivity. And the particle size of the sphere is 3-5mm. Through the arrangement of the ball bodies, the generation of fine particles and dust in the packaging, transporting, using and filling processes is greatly reduced, and the situation that the overall absorption rate is affected due to the fact that the density is not uniform after filling is avoided; through the arrangement of the concave holes, the surface area of the sphere is
