Description

[0001] This application claims priority to Chinese patent application No. 202520272325.9, filed on February 19, 2025, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This utility model relates to a bedding product, and more particularly to a zero-pressure suspended spring pillow. Background Technology

[0003] With the continuous development of technology and the continuous improvement of people's living standards, there are more and more types of pillows on the market. Among them, spring pillows are one type. Spring pillows have good softness and effectively improve the comfort during use, which is loved by consumers.

[0004] Patent CN211093160U discloses a latex spring pillow, including a latex pillow body with an internal cavity and a filling layer inside the cavity. The filling layer includes several layers of bread springs stacked one on top of the other. The outer periphery of the latex pillow body is covered with a fabric layer. By using a latex pillow body, it meets the head comfort needs during sleep and has good antibacterial and anti-mite effects.

[0005] However, the latex pillow body of the aforementioned patented latex spring pillow has no holes and relies solely on its own material properties for breathability. The breathability of the latex pillow body cannot be guaranteed. Moreover, the bread-bag-like springs inside are arranged too tightly. In addition, the existing latex spring pillows have excessively hard surfaces and outdated spring body technology, resulting in excessive resistance and affecting the use effect. Utility Model Content

[0006] Therefore, it is necessary to provide a zero-pressure suspension spring pillow to address the shortcomings of existing technologies.

[0007] A zero-pressure suspended spring pillow includes two main body parts arranged in opposite directions and an inner core sandwiched between the two main body parts. The main body parts are provided with ventilation holes, which are densely distributed on the main body parts. The ventilation holes on the two main body parts correspond one-to-one and are aligned with each other in the vertical direction. The inner core includes several support structures, which are distributed in a layered structure and are regularly distributed in the longitudinal and transverse directions. Each support structure is connected to other adjacent support structures in the transverse and longitudinal directions. Each support structure includes four sub-units. Each sub-unit includes a spring body and a spring sleeve fitted on the spring body. The four sub-units of the same support structure form a four-leaf clover structure. Openings are formed between two adjacent support structures in the transverse direction and between two adjacent support structures in the longitudinal direction.

[0008] In one embodiment, the side of the main body that mates with another main body is provided with a mating surface, which is planar in the extended state.

[0009] In one embodiment, the vent hole penetrates the main body in a direction perpendicular to the mating surface.

[0010] In one embodiment, the main body is further provided with a receiving groove that extends inward from the mating surface.

[0011] In one embodiment, the bottom of the inner core is embedded in a receiving groove of the lower main body, and another main body is fastened to the bottom main body. The receiving grooves on the two main bodies together form an inner space, and the top of the inner core is embedded in a receiving groove of the upper main body.

[0012] In one embodiment, the vent holes are regularly distributed along the longitudinal and transverse directions.

[0013] In one embodiment, the four spring sleeves of the support structure are arranged in two rows, with two spring sleeves in each row.

[0014] In one embodiment, the spring sleeves are provided with opposite corners, and the other two opposite corners of each spring sleeve are arc-shaped transitions to form clearance surfaces. Two horizontally and vertically adjacent spring sleeves on the same support structure are enclosed by clearance surfaces to form clearance openings. The width of the clearance openings gradually narrows from the outside to the inside. One pair of opposite corners of the four spring sleeves are fixed by ultrasonic glueless welding to form connection points.

[0015] In one embodiment, the inner core has its clearance openings in the longitudinal and transverse directions forming the opening, and the butt joint angles 231 of the spring sleeves on the two adjacent support structures are ultrasonically welded together to form a connection point.

[0016] In one embodiment, the main body is made of polyurethane foam.

[0017] In one embodiment, the main body is made of a pressure-sensitive material with a hardness value of 0.

[0018] In one embodiment, the spring body is made of alloy steel wire or titanium alloy steel wire with a wire diameter of less than or equal to 0.8 mm.

[0019] In one embodiment, the height of the spring body is 7-9cm, and the height difference between the front and rear of the spring body installed in the spring sleeve is less than or equal to 2cm. The beneficial effects of this zero-pressure suspended spring pillow are as follows: by setting ventilation holes on the two main bodies, with the inner core sandwiched between them, and the ventilation holes on the two main bodies corresponding and aligned vertically, the breathability of the spring pillow is improved. Based on the ventilation holes, the support structure of the inner core is set as a four-leaf clover structure, with adjacent support structures forming an opening, further improving the breathability of the spring pillow and enhancing its comfort and practicality. The main body has a hardness of 0, the spring body wire diameter is ≤0.8mm, and the front and rear heights are consistent or less than or equal to 2cm, reducing pressure difference and spring resistance, and allowing for quick adaptive conformation to the curves of the neck and head. Furthermore, the spring sleeves on the same support structure are ultrasonically welded without glue, and the spring sleeves between support structures are also ultrasonically welded without glue, making it environmentally friendly and healthy, while also making the overall spring structure more stable within the pillow.

[0031] Please see Figures 1 to 5 This utility model provides a zero-pressure-sensitive suspended spring pillow, comprising two main body parts 10 arranged in opposite directions and an inner core 20 sandwiched between the two main body parts 10. The main body parts 10 are made of zero-pressure-sensitive polyurethane foam or other similar foamed materials. The hardness value of the main body parts 10 is 0 (tested according to Appendix B of GB / T 24451-2020 "Slow-Rebound Soft Polyurethane Foam Plastics" - Determination Method of Temperature and Humidity Sensitivity Index, hardness not detected). Each main body part 10 has a mating surface 11 on one side that mates with the other main body part 10. In the extended state, the mating surface 11 is planar. The main body part 10 also has a receiving groove 12 and a vent hole 13. The receiving groove 12 extends inward from the mating surface 11. The vent hole 13 penetrates the main body part 10 in a direction perpendicular to the mating surface 11. The vent holes 13 are densely distributed on the main body part 10 and are regularly distributed in the longitudinal and transverse directions.

[0032] The inner core 20 includes a plurality of support structures 21, which are distributed in a layered structure and are regularly distributed in the longitudinal and transverse directions. Each support structure 21 is connected to other adjacent support structures 21 in the transverse and longitudinal directions respectively.

[0033] Each support structure 21 includes four sub-units 22. Each sub-unit 22 includes a spring body 24 and a spring sleeve 23 fitted onto the spring body 24. The four sub-units 22 of the same support structure 21 form a four-leaf clover structure. Openings 26 are formed between two adjacent support structures 21 in the horizontal direction and between two adjacent support structures 21 in the vertical direction. The spring body is made of alloy steel wire or titanium alloy steel wire with a wire diameter of less than or equal to 0.8 mm. The height of the spring body is 7 to 9 cm. The height difference between the front and rear of the spring body installed on the spring sleeve is less than or equal to 2 cm.

[0034] Specifically, the four spring sleeves 23 of each support structure 21 are divided into two rows, with two spring sleeves 23 in each row. The diagonal positions of the spring sleeves 23 are respectively provided with butt corners 231. The other two diagonal positions of each spring sleeve 23 are arc-shaped transitions to form clearance surfaces 232. Two horizontally and vertically adjacent spring sleeves 23 on the same support structure 21 are enclosed by clearance surfaces 232 to form clearance openings 25. One pair of butt corners 231 of the four spring sleeves 23 of each spring sleeve 23 are installed and fixed by ultrasonic glueless welding to form connection points, thereby making the four sub-units 22 of the same support structure 21 form a clover structure.

[0035] During assembly, the butt joints 231 of the spring sleeves 23 on adjacent support structures 21 are also ultrasonically welded without glue to form a connection point, thereby forming a complete inner core 20. The clearance openings 25 of adjacent support structures 21 in the longitudinal and transverse directions enclose the opening 26. The spring sleeves are ultrasonically welded without glue, which is environmentally friendly and healthy, and at the same time makes the overall spring structure inside the pillow more stable.

[0036] When the inner core 20 is installed on the two main body parts 10, the bottom of the inner core 20 is embedded in the receiving groove 12 of the lower main body part 10, and then the other main body part 10 is attached to the lower main body part 10. The receiving grooves 12 on the two main body parts 10 enclose an inner space, and the top of the inner core 20 is embedded in the receiving groove 12 of the upper main body part 10. The mating surfaces 11 of the two main body parts 10 are arranged opposite each other and are connected and fixed by glue or other means. The vent holes 13 on the two main body parts 10 correspond one-to-one in the vertical direction and are aligned with each other.

[0037] Understandably, in this embodiment, a receiving groove is provided on the main body 10 to receive the inner core 20. The inner core 20 is relatively thick. In other embodiments, the receiving groove 12 may not be provided on the main body 10, and the inner core 20 is relatively thin. The inner core 20 is directly sandwiched between the two main bodies 10, and the mating surfaces 11 of the two main bodies 10 are connected and fixed near the edge with glue or in other directions.

[0038] The beneficial effects of this novel high-breathability spring pillow are as follows:

[0039] 1. By setting ventilation holes 13 on the two main body parts 10, the inner core 20 is sandwiched between the two main body parts 10. The ventilation holes 13 on the two main body parts 10 correspond one-to-one in the vertical direction and are aligned with each other, thereby improving the breathability of the spring pillow. Based on the ventilation holes 13, the support structure 21 of the inner core 20 is set as a four-leaf clover structure. The two adjacent support structures 21 are surrounded to form an opening 26, thereby further improving the breathability of the spring pillow, improving the comfort of using the spring pillow, and making it highly practical.

[0040] 2. The spring sleeves 23 on the same support structure 21 are welded together by ultrasonic glue-free welding. The spring sleeves 23 between the support structures 21 are also welded together by ultrasonic glue-free welding, which is environmentally friendly and healthy, and at the same time makes the overall spring structure inside the pillow more stable.

[0041] 3. The main body has a hardness of 0, the spring body wire diameter is ≤0.8mm, and the height before and after insertion is consistent or less than or equal to 2cm. This reduces pressure difference and spring resistance, effectively solving the problem that existing technologies have pillows with excessively hard surfaces that cause excessive pressure on the neck and face, making it difficult to quickly adapt to the head and neck curves of different people.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
