[0021] Example: a glue-free mattress includes bed core 1, the comfort layer 2 covered on the surface of the bed core 1, the surface layer wrapped the bed core 1 and the comfort layer 2.

[0022] The difference between the technical scheme and prior art is that: the side of the bed core 1 is provided with surrounding edge 3, the surrounding edge 3 is fixed on the bed core 1 through connecting structure, the connecting structure is glue-free structure, the surrounding edge 3 has elasticity for providing elastic support and protecting the bed core 1.

[0023] In the actual use process of the mattress, the user needs to sit on the surrounding edge 3 when lying down or getting up, the surrounding edge 3 bears most of the weight of the user when the user sits on the surrounding edge 3, and the force area of the surrounding edge 3 is small, so that the single surface area of the surrounding edge 3 is stressed, and the surrounding edge 3 is easy to fall off, therefore, the mattress of prior art needs to use more glue to fix the surrounding edge 3, so that the glue content of the mattress is large.

[0024] Therefore, the technical scheme changes the fixing mode of the surrounding edge 3, fixes the surrounding edge 3 on the side wall of the bed core 1 through the connecting structure, and the connecting structure is glue-free structure, forms glue-free mattress, is favorable for the health of the user, keeps the air smell fresh around the mattress, and is also favorable for the disassembly, recycling and reuse of the mattress.

[0025] Then, the further improvement of the above technical scheme is as follows:

[0026] ​​In practical application, the connecting structure comprises a plurality of connecting pieces 4 arranged at intervals, each of the connecting pieces 4 vertically covers the outer side of the surrounding edge 3, and the two ends of the connecting piece 4 are bent towards the direction of the bed core 1 to cover the upper side and the lower side of the surrounding edge 3 and are fixed to the upper edge and the lower edge of the bed core 1 respectively, and the connecting piece 4 is used to fix the surrounding edge 3 to the side of the bed core 1. The connecting structure uses the connecting piece 4, the connecting piece 4 does not contain glue, and the upper edge and the lower edge of the connecting piece 4 are fixed by physical fixation respectively, so that the connecting structure itself does not contain glue, and the connecting structure does not contain glue when fixing the surrounding edge 3 to the bed core 1. In order to make the mattress not contain glue (at least the part which is easy to overflow or directly contact with the external space does not contain glue), the comfort layer 2 and the surface layer all use glue-free materials.

[0027] In practical application, the connecting piece 4 is a hot melt cotton piece, and the two ends of the connecting piece 4 are fixed to the upper edge and the lower edge of the bed core 1 by means of a gun nail 5. The connecting piece 4 is a hot melt cotton piece, and the two ends of the connecting piece 4 are fixed by means of a gun nail 5, which is beneficial to ensure that the connecting piece 4 has sufficient strength to fix the surrounding edge 3 and ensure that the connecting structure does not contain glue.

[0028] In practical application, at least four connecting pieces 4 are arranged in the length direction of the bed core 1, and at least three connecting pieces 4 are arranged in the width direction of the bed core 1. This is beneficial to ensure that the connecting structure can stably fix the surrounding edge 3, is also beneficial to save the material consumption of the connecting structure, and is further beneficial to improve the installation efficiency of the connecting structure.

[0029] In practical application, the connecting piece 4 arranged in the length direction of the bed core 1 corresponding to the corner of the bed core 1 and the connecting piece 4 arranged in the width direction of the bed core 1 are connected or have a distance less than the interval between the adjacent connecting pieces 4 arranged on the same side of the bed core 1. Since the corner of the bed core 1 is more likely to be subjected to a larger force during use, the surrounding edge 3 of the corner of the bed core 1 needs to have stronger connecting force to ensure use reliability, and therefore the connecting piece 4 in the width direction of the corner of the bed core 1 and the connecting piece 4 in the length direction are as close as possible or even directly contact or overlap, to ensure that the surrounding edge 3 of the corner of the bed core 1 is fixed reliably.

[0030] In practical application, the surrounding edge 3 is a sponge surrounding edge 3, the density of the surrounding edge 3 is 28 kg / m3-45 kg / m3, and the hardness of the surrounding edge 3 is 180 N-300 N. This is beneficial to ensure that the surrounding edge 3 has a better service life, and is further beneficial to improve the service life and overall quality of the mattress.

[0031] In practical application, the bed core 1 is a bed core 1 of a plurality of independent pocket springs or a Bonnell spring bed core 1, and adjacent independent pocket springs are connected by ultrasonic welding. The bed core 1 of the independent spring accommodated in an independent cloth bag and the Bonnell spring bed core 1 formed by ultrasonic welding of adjacent cloth bags are both free of glue, further ensuring that the mattress is free of glue and ensuring that the mattress is healthy to use and convenient to recycle and reuse.

[0032] In practical application, the comfort layer 2 is arranged on one side of the bed core 1 or on opposite sides of the bed core 1, the material of the comfort layer 2 is at least one of latex, sponge and 3D mesh cloth, and the comfort layer 2 is fixed on the bed core 1 by a face layer. This is conducive to ensuring that the comfort layer 2 itself is free of glue, thereby further ensuring that the mattress is free of glue.

[0033] In practical application, the comfort layer 2 can be a single-layer structure or a multi-layer structure. For the multi-layer structure, each layer of the comfort layer 2 can be made of a suitable material according to actual needs.

[0034] In practical application, the comfort layer 2 is arranged in the inner cavity of the comfort layer 2 cover. Alternatively, the comfort layer 2 is directly fixed on the bed core 1 by a face layer. The comfort layer 2 can be a single-layer structure or a multi-layer structure. For the multi-layer structure, in order to have a stable matching relationship and prevent displacement, the multi-layer structure of the comfort layer 2 is fixed by a glue-free back-and-forth penetrating fixing structure. The back-and-forth penetrating fixing structure connects the multi-layer structure of the comfort layer 2 together, and the fixing structure further ensures that the mattress is free of glue.
