Preferably, the above-mentioned cloth wrapping bags 121 are in the shape of "()", that is, each cloth wrapping bag 121 includes a first cloth wrapping block 1211 and a second cloth wrapping block 1212 arranged in mirror image symmetry. The two cloth blocks 1212 are spaced apart, and a cavity for disposing the first spring 122 is formed between them. The first spring 122 is vertically arranged in the cavity formed by the first cloth block 1211 and the second cloth block 1212 of the cloth bag 121 in a direction parallel to the first mattress frame 111 or the second mattress frame 113 . Furthermore, one vertical end of the first spring 122 is in contact with the first fixing frame layer 112 , and the other end is in contact with the second spring layer 13 .

Alternatively, in this embodiment, the height of the first spring layer 12 along the direction from the first fixing frame layer 112 to the second fixing frame layer 114 may be, for example, 5-6 cm.

Further, the second spring layer 13 is a 9-zone zonal spring layer. The 9-zone zonal spring layer includes a plurality of 9-zone zonal springs. Each 9-zone zonal spring includes a spring accommodation bag 131 and a second spring accommodation bag 131 corresponding to the spring accommodation bag 131 . The spring 132 and the spring containing bag 131 are sleeved on the second spring 132 . A plurality of 9-zone zone springs are arranged in a rectangular array in the transverse and longitudinal directions on the 9-zone zone spring layer, and the adjacent 9-zone zone springs are in contact with each other in sequence, thereby playing a role including supporting each other.

It is worth noting that in this embodiment, the cloth-covered spring and the 9-zone zone spring are preferably arranged correspondingly in both the transverse and longitudinal directions on the horizontal plane projected on the first fixing frame layer 112 . The benefits of this arrangement include: when the first fixing frame layer 112 is the lying surface, it is helpful for the 9-zone spring to evenly decompose the pressure on the cloth-wrapped spring and transmit the pressure laterally, thereby alleviating the vertical deformation of the cloth-wrapped spring. Similarly, when the second fixing frame layer 114 is the lying surface, it is beneficial for the cloth-covered spring to evenly decompose the pressure on the 9-zone zone spring and transmit the pressure laterally, thereby alleviating the vertical stress of the 9-zone zone spring. Deformation conditions.

Furthermore, one vertical end of the second spring 132 is in contact with the first spring layer 12 , and the other end is in contact with the second fixing frame layer 114 .

The 9-zone zoning spring in this embodiment has nine sections of support (not shown), which respectively correspond to a total of 9 major parts of the human body: head, shoulders, back, waist, hips, thighs, knees, calves and ankles. By setting up 9-zone springs, it can meet the requirements of human body curves, effectively target the different force conditions of the above-mentioned nine major parts, and avoid problems such as sinking of the spring layer corresponding to the above-mentioned parts when lying down.

Alternatively, in this embodiment, the height of the second spring layer 13 along the direction from the first fixing frame layer 112 to the second fixing frame layer 114 is 10-12 cm. The height of the second spring layer 13 is preferably higher than the height of the first spring layer 12. This arrangement is mainly to ensure that the 9-zone spring can better support and alleviate the sagging of the mattress 20.

More preferably, combined with the heights of the first spring layer 12 and the second spring layer 13 , the width of the 9-zone spring in this embodiment is preferably set to be smaller than the width of the cloth-wrapped spring, that is, the first spring in the same spring containing bag 131 The distance between the accommodating block 1311 and the second accommodating block 1312 is smaller than the distance between the first cloth wrapping block 1211 and the second cloth wrapping block 1212 in the same cloth wrapping bag 121 . This setting is conducive to adjusting and balancing the force and deformation of the springs corresponding to the nine major parts of the human body, making it more in line with the requirements of the human body curve.

Further, please refer to Figure 2. A buffer layer 14 is provided between the first spring layer 12 and the second spring layer 13. A plurality of wavy springs 141 are provided in the buffer layer 14. Each wavy spring 141 includes a plurality of The raised portion 1411 and the recessed portion 1412 are connected in sequence, the raised portion 1411 is used to contact the cloth-wrapped spring, and the recessed portion 1412 is used to contact the 9-zone zoning spring.

Preferably, the height of the buffer layer 14 along the direction from the first fixture layer 112 to the second fixture layer 114 may be, for example, 3-5 cm.

By providing the above-mentioned buffer layer 14, on the one hand, when the cloth-wrapped spring is subjected to a force that is pressed toward the 9-zone spring, the pressure can first be transmitted to the raised portion 1411, so that the raised portion 1411 is pressed in the direction toward the 9-zone spring. Since the wave-shaped spring 141 is arranged laterally, the force exerted on the raised portion 1411 can be laterally transmitted to its adjacent recessed portion 1412, and then transmitted to further raised portions in the lateral direction from near to far. 1411 and recessed portion 1412; at the same time, it is sequentially transmitted in the vertical direction to the 9-zone spring corresponding to the recessed portion 1412, so as to reduce the serious depression caused by the force in the vertical direction of the wrapped spring.

Correspondingly, on the other hand, when the 9-zone zone spring is pressed against the cloth spring, the pressure can first be transmitted to the recessed portion 1412 (at this time, the recessed portion 1412 corresponds to the force of the 9-zone zone spring) In terms of direction, it becomes a "bulge"), causing the recessed portion 1412 to receive a force in the direction toward the cloth-wrapped spring. Since the wave-shaped spring 141 is arranged transversely, the force exerted by the cloth-wrapped spring can be laterally transmitted to its adjacent The raised portion 1411 is then transferred to the further concave portion 1412 and the raised portion 1411 in the lateral direction from near to far; at the same time, it is transferred to the cloth-wrapped spring corresponding to the raised portion 1411 in the vertical direction to weaken 9 Distinguish the depression caused by the force in the vertical direction of the spring.

Furthermore, both the first fixing frame layer 112 and the second fixing frame layer 114 are sponge fixing layers, which are mainly used to fix the first spring layer 12 and the second spring layer 13 respectively. The heights of the first fixing frame layer 112 and the second fixing frame layer 114 along the direction from the first fixing frame layer 112 to the second fixing frame layer 114 can be set to 1.5-2.5 cm. Alternatively, the sponge fixing layer may have a plurality of ventilation holes 1121 along a direction horizontal to the first fixing frame layer 112 .

In addition, please refer to Figures 2 and 3 together. This embodiment also provides a mattress 20, which includes a latex layer 21 and the above-mentioned double spring combined mattress 10. The latex layer 21 covers the surface of the first fixing frame layer 112 on the side away from the first spring layer 12. The height of the latex layer 21 along the direction from the first fixing frame layer 112 to the second fixing frame layer 114 is 4.5-5.5 cm. .

Since the surface area of the latex layer 21 that contacts the human body is higher than that of the ordinary mattress 20, it can evenly distribute the bearing capacity of the human body weight. Therefore, it can not only protect the first spring layer 12 and the second spring layer 13, but also It can also correct poor sleeping posture function. In addition, by providing the latex layer 21, the shock-absorbing effect of the mattress 20 can also be improved, effectively improving sleep quality. Furthermore, the latex layer 21 has good air permeability, which is conducive to improving the air permeability of the air holes 1121 in the sponge fixed layer.

The height of the memory foam layer 22 along the direction from the first fixing frame layer 112 to the second fixing frame layer 114 is 1.5-2.5 cm.

Memory foam has slow rebound mechanical properties. By arranging the memory foam layer 22, on the one hand, it is beneficial to absorb impact force, reduce vibration, and release low rebound force; on the other hand, it can provide uniform surface pressure distribution and adapt to the surface of external pressure through stress relaxation. The shape minimizes the pressure at the highest point, thereby avoiding areas with microcirculatory compression. In addition, the memory sponge has a transparent cell structure, which ensures the breathability and hygroscopicity required by human skin without drilling holes, has appropriate heat preservation properties, and is conducive to improving the breathability of the breathable holes 1121 in the fixed layer of the sponge.

It is worth mentioning that by arranging the latex layer 21 and the memory foam layer 22 respectively on the surface of the first fixing frame layer 112 away from the first spring layer 12 and the second fixing frame layer 114 away from the second spring layer 13 The surface of one side of the mattress 20 can be used as a lying surface, so that the latex layer 21 and the memory foam layer 22 of the mattress 20 can be used as a lying surface, that is, any side of the mattress 20 can be used according to the user's preference.

To sum up, the double spring combined mattress 10 provided by the embodiment of the present invention has good shock absorption effect and stability, can solve the problem that common mattresses 20 are easy to sink, thereby effectively reducing human muscle fatigue and stimulating human sleep nerves. , improve sleep quality.
