The following description with reference to the drawings is provided to help understand the example embodiments of the present application defined by the claims and their equivalents. It includes various specific details to help understanding, but they can only be regarded as exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Moreover, in order to make the description more concise and simple, detailed description of functions and structures well known in the art will be omitted.

[0031] Embodiment 1

[0032] The present embodiment discloses a glueless formaldehyde removal mattress, a structural schematic diagram thereof is shown in Figure 1 and Figure 7 , comprising a glueless core 1, a formaldehyde removal cover 2, and a comfort layer 3; wherein the glueless core 1 and the comfort layer 3 are arranged in the formaldehyde removal cover 2, and the comfort layer 3 is arranged above the glueless core 1. The comfort layer 3 is a soft pad with a specified indentation hardness, which provides a more comfortable rebound feeling for the mattress.

[0033] Please refer to Figure 2 and Figure 3 , the glueless core 1 is composed of a pocket spring group 101 and a steel edge 102 and a protective edge 104 surrounding the pocket spring group 101. Specifically, referring to Figure 4 , each pocket spring 1011 comprises a bag body and a spring loaded into the bag body, wherein two flaky welding parts 1012 are extended out of the two sides of the bag body in the vertical direction, and the two welding parts 1012 are symmetrically arranged. A plurality of pocket springs 1011 are arranged in a straight line and are staggered at two angles, so that the welding parts 1012 of the adjacent pocket springs 1011 are staggered and respectively attached to the front and rear of the pocket spring string, and then the attached welding parts 1012 are connected together by using ultrasonic welding to form an integrated pocket spring string.

[0034] The plurality of pocketed spring strings are arranged side by side in the form of Figure 4 , and the welding portions 1012 of the two pocketed spring strings adjacent in front and back are in contact. Since the pocketed springs 1011 are connected to the pocketed spring strings in two angles alternately, the welding portions 1012 are in front and back of each pocketed spring string, and the welding portions 1012 of the two pocketed spring strings adjacent in front and back are in contact. The welding portions 1012 of the two pocketed spring strings adjacent are welded together by using ultrasonic welding, so that the plurality of pocketed spring strings can form the glue-free connected rectangular pocketed spring group.

[0035] The surrounding steel 102 is the upper and lower two layers of rectangular frames with a certain distance, and the size is equal to the outside dimension of the pocketed spring group 101. The outermost circle of the pocketed springs 1011 of the pocketed spring group 101 is fixedly connected with the surrounding steel 102. Specifically, the upper edge of the pocket of the pocketed spring 1011 is fixed on the upper surrounding steel 102 by the gun nail, and the lower edge of the pocket of the pocketed spring 1011 is fixed on the lower surrounding steel 102 by the gun nail. After the outer side of the pocketed spring group 101 is fixed on the surrounding steel 102, the rigid structure of the surrounding steel can limit the overall size of the pocketed spring group 101, so as to avoid the deformation or sliding of the pocketed spring group 101.

[0036] As shown in Figure 3 , a plurality of straps 103 are fixed on the surrounding steel 102. The straps 103 are arranged in two directions and are fixed by the gun nail 1031 on the upper and lower layers of the surrounding steel 102. The straps 103 are kept a certain distance apart between the upper and lower layers, and the pocketed spring group 101 is clamped between the two layers of straps 103. By clamping the pocketed spring group 101 by the upper and lower layers of straps, the displacement and deformation of the pocketed spring group 101 are limited, so as to prevent the deformation or dislocation of the spring due to long-term use.

[0037] The glue-free core body of the embodiment further comprises a surrounding edge 104, which is composed of four surrounding edge strips, each of which is connected at an angle of 90 degrees to form a closed rectangular frame.

[0038] Referring to Figure 5 , the corner fixing sleeve 105 shown in Figure 6 is further arranged at the corner position of the surrounding steel 102. The middle part of the corner fixing sleeve 105 is bent at an angle of 90 degrees, and the two sides thereof are fixed on the surrounding steel 102 by the gun nail 1051. The corner fixing sleeve 105 is buckled on the outside of the surrounding edge 104, and the junction of the two adjacent surrounding edge strips is limited to the outside of the corner of the surrounding steel 102, so that the surrounding edge 104 surrounds and tightly adheres to the surrounding steel 102, forming an outer frame for protecting the surrounding steel 102.

[0039] The surrounding steel 102 is further fixed with the length direction of the surrounding steel 102 at intervals, and the corner fixing sleeve 105 shown in Figure 6Several intermediate fixing sleeves 106 are shown. The installation diagram of the intermediate fixing sleeve 106 is shown in FIG. 6. Figure 2 As shown, each intermediate fixing sleeve 106 is fixed on the surrounding steel 102 by a gun nail 1061, and the edge guard 104 is fixed on the inner side of the intermediate fixing sleeve 106 by the gun nail 1061, and is further limited around the surrounding steel 102 under the condition that it has been limited by the corner fixing sleeve 105.

[0040] Figure 7 As shown, the structure diagram of the formaldehyde removal outer sleeve 2 of the embodiment is shown, which includes an upper layer 201, a lower layer 203 and a surrounding edge 202, the upper layer 201, the lower layer 203 and the surrounding edge 202 are arranged to form a closed containing space, and at least one of the upper layer 201, the lower layer 203 and the surrounding edge 202 includes a formaldehyde removal material. The formaldehyde removal outer sleeve layer is arranged outside the glue-free core body 1 and the comfort layer 3, and removes the formaldehyde that may be volatilized from the glue-free core body 1 and the comfort layer 3 material, so that the user sleeping on the mattress enjoys excellent air quality.

[0041] In the formaldehyde removal outer sleeve 2, the layer structure of the upper layer 201, the lower layer 203 and the surrounding edge 202 is as shown in FIG. 8. Figure 8 As shown, the upper layer 201, the lower layer 203 and the surrounding edge 202 are composed of three layers of materials, i.e. an outer cloth 501, an inner cloth 503 and a filler 502 arranged between the outer cloth and the inner cloth, and are sewn together by a line sewing process. At least one of the outer cloth 501, the inner cloth 503 and the filler 502 is composed of a formaldehyde removal material, so that the formaldehyde removal outer sleeve 2 can remove the formaldehyde emitted.

[0042] In addition, the upper surface of the upper layer 201 is one or more of moisture-absorbing and sweat-releasing fibers, bamboo fibers and Tencel fibers, which provides a good sleeping feeling and has the effects of air permeability and moisture absorption.

[0043] Specifically, when the inner cloth or the outer cloth is composed of a formaldehyde removal material, the inner cloth or the outer cloth can adopt a fabric woven by a formaldehyde removal functional fiber; when the filler is a formaldehyde removal layer, a formaldehyde removal functional sponge can be used; and when the filler is glue-free cotton and composed of a formaldehyde removal material, the filler can adopt a glue-free cotton block supported by a formaldehyde removal functional fiber.

[0044] The glue-free formaldehyde removal mattress of the embodiment connects the pocketed springs into one by ultrasonic welding, without the need for glue bonding, solves the problem that the bonded part falls off due to aging of the glue in the traditional mattress, and avoids the pollution of harmful gases released by the glue to the indoor air. At the same time, the formaldehyde removal outer sleeve in the embodiment can further remove the formaldehyde that may be volatilized from the materials inside the mattress, so that the user sleeping on the mattress enjoys more excellent air quality.

[0045] Embodiment 2

[0046] This embodiment provides a highly elastic, glue-free mattress, the main difference being the addition of an inner sleeve 4 in its structure. For example... Figure 9 As shown, the inner sleeve 4 includes a top mesh 401, a bottom mesh 402, and an inner sleeve edging 403. The center of the inner sleeve edging 403 is hollow. The edge of the top mesh 401 is sewn to the edge of the hollowed-out portion on the upper surface of the inner sleeve edging 403, and the edge of the bottom mesh 402 is sewn to the edge of the hollowed-out portion on the lower surface of the inner sleeve edging 403. The glue-free core 1 is inserted into the inner sleeve 4, which is composed of the top mesh 401, the bottom mesh 402, and the inner sleeve edging 403. The comfort layer 3 is placed on top of the inner sleeve 4, and both are inserted into the accommodating space formed by the upper layer 2, the lower layer 4, and the edging 5.

[0047] The top mesh 401 and bottom mesh 402 are made of hexagonal mesh with the edges of each hexagon protruding upwards, forming a high-friction texture. They are located on the upper and lower surfaces of the inner cover 4, respectively. The inner cover 4 not only provides protection for the glue-free core 1, but also applies greater friction to the comfort layer 3 through the high-friction texture of the top mesh 401, preventing it from slipping and thus improving the overall stability of the mattress.
