Description

Technical Field

[0001] This utility model relates to a mat, especially a seat cushion, and more particularly to a mat with anti-collapse and breathable channels. Background Technology

[0002] Traditional inflatable mats often use a single material layer, which is prone to permanent deformation after long-term pressure. Some traditional inflatable mats attempt to improve support by thickening the material layer, but this further deteriorates the breathability of the mat. There is a conflict between breathability and anti-collapse performance in traditional inflatable mats. While conventional open-pore ventilation designs can improve air circulation, they greatly weaken structural stability. On the other hand, closed-pore designs enhance support, but they significantly trap moisture and are prone to mold growth. Therefore, there is an urgent need in the market for a mat that can provide support and prevent collapse while also having excellent breathability.

[0003] Chinese utility model patent CN 207784780 U discloses an inflatable multifunctional mat. The mat includes a mat cover with a valve and a liner. The mat cover is divided into at least two separate areas by at least one seam and has two parallel longitudinal edges extending along a separable locking device. While this mat provides some support, prolonged sitting on it can lead to poor breathability, moisture retention, and mold growth. Utility Model Content

[0004] This invention aims to overcome the shortcomings of the prior art by providing a cushion with anti-collapse, breathable, and long-term comfortable sitting cushion that meets the need for long-term comfort of the back or buttocks whether lying down or sitting, without heat accumulation.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This anti-collapse mat with ventilation channels includes an inflatable bladder. A set of equally spaced ventilation holes are opened on the inflatable bladder and penetrate through the upper and lower parts of the inflatable bladder. A set of connectors paired with each ventilation hole are provided inside the inflatable bladder. The connectors include one or more ventilation modules that are glued and stacked together. The ventilation module includes an upper anti-leakage patch and a lower anti-leakage patch. Both the upper and lower anti-leakage patches have through holes in their centers. The middle parts of the upper and lower anti-leakage patches are glued together and the two through holes are concentrically arranged. The outer end of the uppermost upper anti-leakage patch is glued to the upper mold of the inflatable bladder, and the outer end of the lowermost lower anti-leakage patch is glued to the lower mold of the inflatable bladder. The through holes communicate with the ventilation holes. The purpose of the ventilation holes here is to improve the breathability of the mat; the purpose of the connectors here is to support the mat after it is inflated, preventing it from collapsing and deforming after prolonged sitting; the purpose of using multiple expandable ventilation modules here is to support mats of different thicknesses; the purpose of the through holes and ventilation holes here is to allow for smooth air circulation, making it comfortable and not stuffy even when lying or sitting for a long time.

[0006] Further improvements include the addition of a flexible plastic sheet bonded to the center between the upper and lower air-proof patches. This flexible plastic sheet has a hole in its center that connects to the ventilation holes. The purpose of this flexible plastic sheet is to increase the stability between the upper and lower air-proof patches after the mat is inflated, thereby increasing the anti-collapse support and ensuring the stability of the ventilation holes, thus improving the mat's breathability.

[0007] The outer ends of the topmost leak-proof patch and the upper fabric of the airbag, the outer ends of the bottommost leak-proof patch and the lower fabric of the airbag, the top and bottom leak-proof patches and the soft plastic sheet, and the outer ends of the bottom leak-proof patch on the top side of the ventilation module and the top leak-proof patch on the bottom side of the ventilation module are all fixed by heat fusion welding. The purpose of using heat fusion welding here is to ensure that materials of the same material are heat-fused together, making them less prone to detachment and aging, resulting in higher strength and a longer service life.

[0008] Further improvements include the addition of a pair of opposing straps fixed to the inflatable cushion. These straps are designed to secure the cushion to a chair or bed, preventing it from slipping and falling during use.

[0009] Further improvements include a recessed area, wider at the top and narrower at the bottom, in the lower right corner of the air bladder. A one-way valve inflation nozzle is installed within this recess. The purpose of this recess and the one-way valve inflation nozzle is not only to allow the nozzle to inflate and deflate the pad, but also to prevent the nozzle from being touched, bumped, or bent during use, thus avoiding any cracking or leakage at the connection between the nozzle and the pad.

[0010] The beneficial effects of this utility model are:

[0011] 1) The connectors provide support for the inflatable bladder after it is inflated, preventing it from collapsing after prolonged sitting or lying down.

[0012] 2) Through the perforations and ventilation holes, the mat can remain breathable and comfortable even after long-term use, preventing the buttocks and back from becoming hot and uncomfortable;

[0013] 3) The notch and one-way valve inflation nozzle not only allow the one-way valve inflation nozzle to inflate and deflate the pad, but also prevent the one-way valve inflation nozzle from being touched, bumped, or bent during use, thus avoiding cracking and leakage at the joint between the one-way valve inflation nozzle and the inflation bladder.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] Referring to the attached diagram; this anti-collapse mat with ventilation channels includes an inflatable bladder 1, on which a set of equally spaced ventilation holes 1-1 are opened and penetrate the upper and lower parts of the inflatable bladder 1. Inside the inflatable bladder 1, there is a set of connectors 2 that are paired with each ventilation hole 1-1; the connectors 2 include one or more ventilation modules 2-1 that are glued and stacked together; the ventilation module 2-1 includes an upper anti-leakage patch 2-1a and a lower anti-leakage patch 2-1a. b. Both the upper anti-leakage patch 2-1a and the lower anti-leakage patch 2-1b have through holes 2-1c in their centers. The upper anti-leakage patch 2-1a and the lower anti-leakage patch 2-1b are glued together in the middle, and the two through holes 2-1c are set concentrically. The outer end of the uppermost anti-leakage patch 2-1a is glued to the upper fabric of the airbag 1, and the outer end of the lowermost anti-leakage patch 2-1b is glued to the lower fabric of the airbag 1. The through hole 2-1c is connected to the vent hole 1-1.

[0023] A plastic flexible board 2-1d is adhered to the center position between the upper air-proof patch 2-1a and the lower air-proof patch 2-1b. The center of the plastic flexible board 2-1d has a hole 2-1e that communicates with the vent hole 1-1.

[0024] The outer end of the uppermost leak-proof patch 2-1a is fixed to the upper fabric of the airbag 1; the outer end of the lowermost leak-proof patch 2-1b is fixed to the lower fabric of the airbag 1; the upper and lower leak-proof patches 2-1a and 2-1b are fixed to the plastic soft board 2-1d; and the outer end of the lower leak-proof patch 2-1b on the upper side of the ventilation module 2-1 is fixed to the outer end of the upper leak-proof patch 2-1a on the lower side of the ventilation module 2-1.

[0025] A pair of oppositely positioned straps 3 are fixed to the inflatable bladder 1.

[0026] The lower right corner of the airbag 1 has a notch 1-2 that is larger at the top and smaller at the bottom, and a one-way valve air nozzle 4 is installed inside the notch 1-2.

[0027] The working principle of this utility model is as follows: First, an air pump (not shown in the figure) is used to inflate the mat through a hose installed at the one-way valve inflation nozzle 4. After the mat inflates, the connecting piece 2 expands and supports the mat. Air can pass through the hole 2-1e, which not only provides good anti-collapse support but also has strong breathability, making it comfortable to lie or sit for long periods without feeling stuffy. The connecting piece 2 supports the inflatable bladder 1 after inflation, preventing it from collapsing after prolonged sitting or lying down. Through the through hole 2-1c, the ventilation hole 1-1, and the hole 2-1e, the mat can also maintain its shape even after long-term use. It maintains breathability and comfort, preventing discomfort and overheating of the buttocks and back. The notches 1-2 and the one-way valve inflation nozzle 4 not only allow for inflation and deflation of the mat, but also ensure that the nozzle is recessed within the notches, preventing accidental contact, bumps, or bending during use. This avoids cracking and leakage at the connection between the nozzle and the inflation bladder 1. For thicker mats, multiple breathable support modules 2-1 can be welded together to provide anti-collapse support and breathability, offering strong versatility (e.g., ...). Figure 6 (As shown).
