[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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 of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-3 , a through-hole breathable foam structure, including a cotton body 1, further comprising: a first through-hole 2, the first through-hole 2 is arranged on the cotton body 1, and the first through-hole 2 is symmetrically arranged near the outer side of the cotton body 1, and the first through-hole 2 can assist the cotton body 1 to breathe; a second through-hole 3, the second through-hole 3 is arranged on the cotton body 1, and the second through-hole 3 is symmetrically arranged inside the first through-hole 2, the cross-section of the second through-hole 3 is in a special shape, and the second through-hole 3 can assist the cotton body 1 to breathe; a groove 7, the groove 7 is opened on both sides of the cotton body 1, and the groove 7 runs through the cotton body 1; the first through-hole 2 and the second through-hole 3 opened on the cotton body 1 achieve the effect of ventilation. The first through-hole 2 and the second through-hole 3 vertically penetrate the cotton body 1, and the second through-hole 3 is in a special shape. When the cotton body 1 is squeezed, the internal air can be discharged through the first through-hole 2 and the second through-hole 3. When the cotton body 1 is not squeezed, it breathes through the first through-hole 2 and the second through-hole 3. The groove 7 on the side of the cotton body 1 can provide more supporting surfaces relative to the cotton body 1 when under pressure.

[0024] As Figure 2 shown, the upper and lower ends of the second through-hole 3 are symmetrically distributed, and convex grooves 4 are opened at both the upper and lower ends inside the second through-hole 3; when the cotton body 1 is squeezed from the upper end, the convex grooves 4 are deformed under pressure, and the convex grooves 4 expand outward to inhale more air. When the cotton body 1 expands, the inhaled air can be discharged through the resilience of the convex grooves 4, thereby achieving the effects of exhaust and ventilation.

[0025] As Figure 2 shown, a concave groove 5 is opened in the middle of the second through-hole 3, and the concave groove 5 is communicated with the convex groove 4; when the cotton body 1 is squeezed from the upper end, the concave groove 5 in the middle of the cotton body 1 is squeezed inward, assisting the cavity in the convex groove 4 to form a negative pressure, and thus facilitating the ventilation and exhaust of the cotton body 1 better.

[0026] As Figure 2 shown, a communication hole 6 is horizontally opened inside the cotton body 1, and the communication hole 6 communicates with the first through-hole 2 and the second through-hole 3, and the upper and lower ends of the communication hole 6 are symmetrically arranged; the communication hole 6 communicates with the first through-hole 2 and the second through-hole 3, enabling the overall internal structure of the cotton body 1 to be connected, and thus achieving a better connected ventilation effect.

[0027] As Figure 2As shown, the first through-hole 2 is arranged through the groove 7, distributed at the four corners of the cotton body 1, and the first through-hole 2 is arc-shaped. When the cotton body 1 is in use, air enters the cotton body 1 from top, bottom, left and right, and the distribution position of the first through-hole 2 facilitates the exhaust and ventilation of air.

[0028] As Figure 2 shown, the number of the first through-holes 2 is set to be multiple, and the spacing is equal. The second through-hole 3 is arranged corresponding to the position of the first through-hole 2. The multiple first through-holes 2 and second through-holes 3 can enhance the exhaust and ventilation effects inside the cotton body 1.

[0029] As Figure 2 shown, a through-hole 8 is opened in the middle of the cotton body 1. The cross-section of the through-hole 8 is elliptical, and the two ends of the minor axis of the through-hole 8 are parallel to the groove 7. The elliptical through-hole 8 can quickly restore its original shape through the through-hole 8 after the side of the cotton body 1 is squeezed, thus achieving the effect of quick restoration.

[0030] As Figure 2 shown, the cross-sections of the first through-hole 2, the second through-hole 3 and the communication hole 6 can be circular, triangular, quadrilateral, pentagonal, etc. The multi-shaped settings of the first through-hole 2, the second through-hole 3 and the communication hole 6 can adapt to different usage scenarios and make the appearance of the outer side of the cotton body 1 different.

[0031] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
