[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , in the embodiment of the present utility model, a central extraction type toilet paper for a user to extract paper towels from the center of the toilet paper includes a cylindrical toilet paper 1 formed by winding long strip paper towels. A hollow cavity is axially provided in the center of the cylindrical toilet paper 1, and a supporting airbag 2 for preventing the paper towels from collapsing is arranged in the hollow cavity.

[0020] When the present utility model realizes central extraction of the toilet paper, the gas in the supporting airbag is released or the supporting airbag is directly extracted, with simple operation and convenient use.

[0021] The toilet paper in the present utility model does not require a central paper tube, and a supporting airbag is used to replace the central paper tube, resulting in lower production costs.

[0022] The supporting airbag 2 for preventing the paper towels from collapsing abuts against the paper towels on the wall surface of the hollow cavity.

[0023] The diameter of the hollow cavity is 2 - 5 cm.

[0024] As an embodiment of the present utility model, both ends of the long strip paper towel are an inner end 3 at the center of the cylindrical toilet paper 1 and an outer end 4 at the outermost side of the cylindrical toilet paper 1. The inner end 3 of the long strip paper towel is connected to the supporting airbag 2. When the supporting airbag 2 is extracted from the hollow cavity, the inner end 3 of the long strip paper towel is taken out, realizing paper extraction from the center of the cylindrical toilet paper 1.

[0025] As another embodiment of the present utility model, both ends of the long strip of tissue paper are an inner end 3 located at the center of the cylindrical rolled paper 1 and an outer end 4 located at the outermost side of the cylindrical rolled paper 1.
