Description

Technical Field

[0001] This utility model relates to the field of pillow technology, and in particular to a breathable foam spring pillow. Background Technology

[0002] A foam spring breathable pillow is a composite functional pillow that combines multiple materials and structures. Its core features are the integration of the comfortable support of foam, the elasticity of springs, and breathable design. Its core functions include dynamic support, high-efficiency breathability, and durability against collapse.

[0003] Traditional pillows mostly use a single sponge or spring structure, which has problems such as poor breathability, non-adjustable support, and easy collapse. Existing spring pillows have a certain degree of elasticity, but lack three-dimensional ventilation channels; while sponge pillows are soft but have poor heat dissipation. Therefore, we have proposed a sponge spring breathable pillow. Utility Model Content

The wire diameter of the conical spiral spring is 0.8-1.2mm, and the spacing between adjacent conical spiral springs 31 is 1.2-1.5 times the spring diameter.

[0014] As a technical solution of the sponge spring breathable pillow of this utility model, the substrate is honeycomb-shaped, and each honeycomb unit on the substrate corresponds to one conical spiral spring, and the wall thickness of the honeycomb unit is 0.5-0.8mm.

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1-4 A foam spring breathable pillow is provided, which includes an upper foam layer 1, which is made of high-density memory foam and has an array of through-ventilation holes 101.

[0028] The intermediate breathable connecting column group includes multiple breathable connecting columns 21 arranged in a rectangular array, and one end of the breathable connecting column 21 is installed on the upper layer of cotton 1.

[0029] The bottom support spring group includes multiple conical helical springs 31 arranged in a rectangular array, and the breathable connecting column 21 penetrates vertically through the upper cotton layer 1 and is coaxially connected with the conical helical springs 31.

[0030] The substrate 4 is installed below the bottom support spring assembly. In application, the three-layer structure of the upper layer of foam 1, the middle breathable connecting column assembly and the bottom support spring assembly forms a three-dimensional breathable channel, which simultaneously achieves the soft fit of the sponge and the dynamic support of the spring. The coaxial design of the conical spiral spring 31 and the breathable connecting column 21 can ensure uniform pressure transmission and avoid local collapse.

[0031] Reference Figure 1 and Figure 4 The bottom of the upper layer 1 has a positioning blind hole 102 corresponding to the breathable connecting post 21, and the depth of the positioning blind hole 102 is one-third to one-half of the length of the breathable connecting post 21. The positioning blind hole 102 is formed by hot pressing with a mold. In application, the depth limitation of the positioning blind hole 102 can ensure the stability of the breathable connecting post 21 being embedded, and prevent excessive compression from affecting the structural strength of the breathable connecting post 21.

[0032] Reference Figure 2 and Figure 3 The ventilated connecting post 21 is a rigid plastic hollow tube (rigid polypropylene hollow tube). The tube wall of the ventilated connecting post 21 has ventilated windows 211 arranged in a circumferential array. The bottom outer surface of the ventilated connecting post 21 is equipped with a snap-fit ​​flange 212 that mates with the top of the conical helical spring 31. A buffer area is reserved between the bottom of the ventilated connecting post 21 and the substrate 4. In application, the rigid plastic hollow tube, together with the ventilated windows 211 arranged in a circumferential array, provides rigid support while increasing lateral airflow exchange. The snap-fit ​​flange 212 design avoids hard contact between the conical helical spring 31 and the ventilated connecting post 21, and the buffer area reduces the risk of metal fatigue.

[0033] Reference Figure 1 , Figure 2 as well as Figure 4 The upper diameter of the conical helical spring 31 is smaller than the lower diameter, and the inner cavity of the conical helical spring 31 forms an inverted conical airflow channel. The wire diameter of the conical helical spring 31 is 0.8-1.2mm, and the spacing between adjacent conical helical springs 31 is 1.2-1.5 times the spring diameter. In application, the inverted conical airflow channel of the conical helical spring 31, combined with a spacing of 1.2-1.5 times, can improve the vertical air convection efficiency. The wire diameter of 0.8-1.2mm can balance elasticity and durability.

[0034] Reference Figure 1 , Figure 2 as well as Figure 4 The substrate 4 is honeycomb-shaped and can be a honeycomb ABS substrate. Each honeycomb unit on the substrate 4 corresponds to a conical helical spring 31. The wall thickness of the honeycomb unit is 0.5-0.8mm. The bottom edge of the substrate 4 is provided with a quick-release buckle 401, which is adapted to the slot structure on the inner wall of the pillowcase. The edge of the substrate 4 is injection molded with elastic buckles to form a plug-in connection with the nylon slots on the inner wall of the pillowcase. In application, the layout of the honeycomb substrate units corresponding to the conical helical springs 31 disperses pressure and strengthens the substrate 4's resistance to deformation. The 0.5-0.8mm wall thickness balances lightweight and load-bearing capacity. At the same time, the buckle 401 can realize the quick disassembly and assembly of the substrate 4, which is convenient for cleaning and maintenance.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
