[0024] Referring to Figures 1 to 5 As shown, zero glue breathable durable bed core, including multiple rows of bagged spring string 1, multiple rows of bagged spring string 1 is arranged and is connected, and each row bagged spring string 1 includes breathable cloth bag 2 and a plurality of springs 3, and a plurality of springs 3 are sequentially arranged in the breathable cloth bag 2 along the length direction, and a plurality of groups of welding seam structures are fused on the breathable cloth bag 2, and a plurality of springs 3 are encapsulated by a plurality of groups of welding seam structures; the breathable cloth bag 2 is interwoven by fabric containing hot melt material, and the fabric interwoven place forms a breathable pore.

[0025] The breathable cloth bag 2 in the bed core is made of polyester cotton fabric, which is woven by the hot melt material, has good air permeability, high strength, good elasticity, wrinkle resistance and wear resistance, is firm and durable, and will not appear powdering after long-term use.

[0026] Each spring 3 includes an upper end support section 31 and a main body support section 32, wherein the pitch of the main body support section 32 is greater than the pitch of the upper end support section 31, and the length of the main body support section 32 accounts for one half to two thirds of the length of the whole spring 3.

[0027] Under the condition of the same steel wire diameter, the main body support section 32 is formed by large pitch, which can make the spring force greater and the lying feeling harder, and the upper end support section 31 is formed by small pitch, which can make the spring force smaller and the lying feeling softer, so that the spring can realize two kinds of hardness, and the human body can be more fitted to the human body curve when lying on the core, so that the user can lie more comfortably.

[0028] Each group of welding seam structures includes a left welding seam 21 and a right welding seam 22, and the left welding seam 21 and the right welding seam 22 are arranged side by side and are separated from each other, and each spring 3 is independently encapsulated and separated from the left welding seam 21 of the adjacent group by the right welding seam 22; each spring 3 is encapsulated by two welding seams, so that the encapsulation is more firm, even if one of the welding seams breaks, the other welding seam can still separate the two springs, which can improve the double protection effect.

[0029] The two rows of pocketed spring strings 1 are connected by the middle welding seam 23 at the same interval of the number of springs 3, the middle welding seam 23 is hot-melted between the left welding seam 21 and the right welding seam 22 and is arranged at intervals; when the two rows of pocketed spring strings 1 are connected, the left welding seam 21 and the right welding seam 22 are left with positions, so that the middle welding seam 23 is not overlapped on the left welding seam 21 or the right welding seam 22 when welding, preventing the air-permeable cloth bag 2 from being broken due to excessive hot-melting.

[0030] The two ends of the spring 3 are bent inward relative to the outermost coil 33; this structure prevents the spring ends from protruding laterally of the spring, avoiding the spring ends from piercing or scratching the side of the air-permeable cloth bag 2.

[0031] The middle width of the outer diameter of the spring 3 is greater than the width of the two ends, and the width decreases linearly from the middle to the two ends; this structure enables the spring 3 to have different numbers of springs 3 at different positions, which helps the spring 3 to maintain up-and-down movement when compressed and is not prone to axial deflection.

[0032] The pitch of the main support section 32 is H1, and 40mm≤H1≤80mm, in this embodiment, H1 is about equal to 60mm; the pitch of the upper end support section 31 is H2, and 0mm<H2<40mm, and H2 is about equal to 30mm.
