Description

Technical Field

[0001] This utility model relates to the field of mattress structure technology, and in particular to a glue-free spring mattress. Background Technology

[0002] The market offers a wide variety of mattresses, among which spring mattresses are widely used due to their excellent support and durability. To avoid the release of harmful gases from glue and improve environmental performance, more and more mattress products are adopting a "glue-free" structure, which means fixing and bonding the internal layers through physical interlocking, hot pressing, and mechanical connection, making the mattress greener and healthier.

[0003] However, while these glue-free spring mattresses can guarantee mechanical performance and environmental protection, they generally lack the ability to cope with the consequences of water seepage. In actual use, if the mattress is spilled with liquids such as tea, urine, or beverages, the water can easily seep through the surface of the mattress into the internal filling material or spring area and remain in the gaps of the internal structure. In particular, the glue-free structure is more likely to form "internal water accumulation" after water intrusion due to the lack of sealing between layers, which can lead to problems such as mold, odor, and bacteria growth, and even accelerate the corrosion and performance degradation of the metal springs, affecting the lifespan of the mattress.

[0004] Although some products currently use waterproof fabrics or removable and washable covers, most are still mainly passive protection and lack a system design that actively guides, removes, and dries moisture after it enters. Users usually have to wait for it to air dry naturally or use a hair dryer to force it to heat up. However, because the inside of the mattress is sealed and the heat cannot circulate, the drying efficiency is often low and the operation is inconvenient. Utility Model Content

[0005] This invention aims to provide a glue-free spring mattress to solve the problems mentioned in the background art. By incorporating water-absorbing columns, through-holes, a cover plate, and an exhaust mesh into the glue-free spring mattress, this invention constructs an internal dehumidification system that integrates rapid water absorption, hot air introduction, and closed drying. This solves the problems of low drying efficiency and moldy odors in existing mattresses after water seepage. The water-absorbing columns are positioned close to the through-holes, facilitating near-field absorption and dehumidification. Combined with the staggered through-holes and strip-shaped holes, this improves the circulation efficiency of hot air within the mattress, enabling rapid localized and targeted drying of leaks. Simultaneously, the water-absorbing columns and spring frame are isolated from each other, ensuring that the mattress support structure is not affected by moisture, thereby extending its service life and optimizing the user experience.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A glue-free spring mattress includes an outer layer. Multiple through holes and multiple strip-shaped holes are respectively formed on both sides of the outer end of the outer layer. Multiple connecting plates are connected to the outer end of the outer layer, surrounding the through holes. A cover plate is detachably connected to the connecting plate, covering the through holes. An air vent is connected to the inner end of each strip-shaped hole. Multiple absorbent columns arranged in a matrix are connected to the inner end of the outer layer, with both ends of each absorbent column abutting against the upper and lower ends of the inner wall of the outer layer.

[0008] Preferably, the through holes and strip holes are arranged alternately.

[0009] Preferably, the inner end of the connecting plate is engraved with a threaded groove, and the cover plate is threadedly connected to the connecting plate.

[0010] Preferably, the water-absorbing column is positioned near the through hole.

[0011] Preferably, a spring frame is connected inside the outer layer, and the water-absorbing column and the spring do not contact each other.

[0012] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0013] This invention constructs an internal dehumidification system that integrates rapid water absorption, hot air introduction, and closed drying by incorporating water-absorbing columns, through holes, a cover plate, and an exhaust mesh into a glue-free spring mattress. This solves the problems of low drying efficiency and moldy odors in existing mattresses after water seepage. The water-absorbing columns are positioned close to the through holes, facilitating near-field adsorption and dehumidification. Combined with the staggered through holes and strip-shaped holes, this improves the circulation efficiency of hot air inside the mattress, enabling rapid localization and targeted drying of localized water seepage. At the same time, the water-absorbing columns are isolated from the spring frame, ensuring that the mattress support structure is not affected by moisture, thereby extending its service life and optimizing the user experience.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0019] like Figure 1-3 The glue-free spring mattress shown includes an outer layer 1. Both sides of the outer end of the outer layer 1 are provided with multiple through holes 2 and multiple strip holes 5. Multiple connecting plates 3 are connected to the outer end of the outer layer 1. The connecting plates 3 are arranged around the through holes 2, and a cover plate 4 is detachably connected to the connecting plate 3. The cover plate 4 covers the through holes 2. An exhaust mesh 6 is connected to the inner end of the strip holes 5. Multiple water-absorbing columns 7 are connected to the inner end of the outer layer 1 in a matrix arrangement. The two ends of the water-absorbing columns 7 abut against the upper and lower ends of the inner wall of the outer layer 1, respectively.

[0020] Currently, glue-free spring mattresses are favored for their environmental friendliness and health benefits. They use physical bonding, heat pressing, or mechanical connections to fix the layers, avoiding the release of harmful gases from glue. However, they generally suffer from the problem of difficult water treatment after spillage. Liquid spills easily seep into the unsealed interlayer structure, accumulating inside and causing mold, odors, bacterial growth, and even spring corrosion, severely impacting lifespan. Existing products mostly rely solely on waterproof fabrics or removable washable covers, lacking effective moisture-wicking, dehumidifying, and active drying mechanisms. Users often have to rely on natural air drying or a hairdryer, which is inefficient and cumbersome.

[0021] This solution integrates multiple structural elements, including absorbent columns 7, through holes 2, and exhaust nets 6, into a glue-free mattress to create a comprehensive internal moisture-wicking system that combines rapid moisture absorption, active air venting, and external auxiliary drying. The absorbent columns 7, made of highly absorbent material, quickly absorb moisture from the seepage point, preventing it from spreading on the outer cover 1 or dripping into the mattress. The exhaust nets 6 form airflow channels, allowing users to insert external heat sources such as hair dryers into the through holes 2 via the removed cover 4. This creates a closed-loop hot air circulation system, effectively improving the mattress's internal drying efficiency, addressing the technical challenge of drying after seepage in glue-free mattresses, extending mattress lifespan, and enhancing user experience.

[0022] Through holes 2 and strip holes 5 are arranged alternately.

[0023] The staggered arrangement of through holes 2 and strip holes 5 in this design allows airflow to form a staggered circulation path on both sides of the mattress, avoiding the problem of localized high temperatures and insufficient drying in other areas caused by hot air passing through in a straight line. Through the staggered arrangement of through holes 2 and strip holes 5, combined with the matrix distribution area where the internal water-absorbing columns 7 are located, hot air can be evenly diffused inside the mattress and fully contact the water accumulation area, which helps to improve the overall drying efficiency and reduce the risk of mold or odor caused by localized dampness inside the mattress. This works closely with the core technology of "active dehumidification".

[0024] The inner end of the connecting plate 3 is engraved with a threaded groove, and the cover plate 4 is threadedly connected to the connecting plate 3.

[0025] In this design, the cover plate 4, which is threadedly connected to the connecting plate 3, is easy to disassemble and can be used to seal the through hole 2 in daily use to prevent foreign objects from entering the mattress.

[0026] The water-absorbing column 7 is positioned near the through hole 2.

[0027] The arrangement of the absorbent column 7 and the through hole 2 in this solution helps to achieve the linkage effect of "near adsorption - near dehumidification". When the liquid seeps into the mattress, the user inserts the hot air blower into the through hole 2 closest to the seepage position. Then, the hot air flow at the through hole 2 quickly dries the absorbent column 7 that has absorbed water, effectively shortening the drying time.

[0028] The outer layer 1 is internally connected to a spring frame, and the water-absorbing column 7 does not contact the spring.

[0029] In this design, the water-absorbing column 7 is positioned far from the spring, ensuring that it will not affect the core spring support system of the mattress due to moisture erosion or water absorption and expansion during the moisture-wicking and drying process. This avoids problems such as spring rust and loss of elasticity. The water-absorbing column 7 is independently placed outside the spring, which can quickly absorb water accumulated in the interlayer without interfering with the normal compression and recovery of the spring, effectively achieving "independent structure and coordinated function".
