[0001] The utility model relates to the technical field of airbag mattresses, in particular to an airbag mattress with an explosion-proof pressure relief structure. Background Art

[0002] As a new type of bedding, airbag mattresses have gradually attracted attention in the market in recent years. They use the internal airbag structure to adjust the hardness and comfort of the mattress by inflation, achieving dual adjustment of the softness and support of the mattress, providing users with a more comfortable sleeping experience.

[0003] However, with the increasing popularity of airbag mattresses, safety concerns have become increasingly prominent. This is especially true when the airbag is exposed to high pressure or high temperature. Both high and high pressure can increase internal gas pressure. When the internal gas pressure exceeds the mattress's tolerance, these mattresses lack effective explosion-proof and pressure-relief mechanisms, which can easily lead to airbag rupture or even explosion, posing a safety hazard to users. To address this, we have developed an airbag mattress with an explosion-proof and pressure-relief structure. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] Please refer to Figures 1-4 The present application provides a technical solution: an air bag mattress with an anti-explosion pressure relief structure, comprising an air bag mattress body 1, wherein the air bag mattress body 1 is provided with a pressure relief exhaust assembly 2, the pressure relief exhaust assembly 2 comprises an inner sleeve 20 fixedly installed on the air bag mattress body 1, a support disc 21 fixedly installed on the inner wall of the inner sleeve 20, a plurality of annularly and equidistantly arranged air holes 211 provided on the support disc 21, the air holes 211 being used for air passage operation, a conical sleeve 23 fixedly installed on the inner wall of the bottom tube body of the inner sleeve 20, an outer sleeve 24 fixedly installed at the bottom end of the inner sleeve 20, a plurality of linearly and equidistantly arranged fixed rings 252 fixedly installed on the inner wall of the outer sleeve 24, a center sleeve 25 fixedly installed at the center position of the plurality of fixed rings 252, an exhaust hole 253 provided on the fixed ring 252 and connected with the outside, a blocking ball 27 provided at the conical sleeve 23 part, a tension spring 28 fixedly installed between the blocking ball 27 and the support disc 21, the tension spring 28 penetrating through the conical sleeve 23, so as to realize the blocking operation of the conical sleeve 23 part by the blocking ball 27, when the gas pressure in the air bag mattress body 1 increases, the gas can push open the blocking ball 27, at this time, the gas in the air bag mattress body 1 can be normally discharged outward, and the anti-explosion pressure relief protection effect is achieved.

[0026] In the embodiment, the inner diameter of the air hole 211 is greater than 0.5 mm, and the number of the air holes 211 is 4-12, so that the exhaust operation along the air hole 211 part is more smooth.

[0027] Specifically, the conical sleeve 23 is in a hollow circular truncated cone shape, and the inner diameter of the conical sleeve 23 increases from top to bottom; the inner wall of the conical sleeve 23 is provided with a sealing pad layer 231, the blocking ball 27 abuts against the sealing pad layer 231 for blocking operation, so as to avoid gas leakage.

[0028] Further, the size of the blocking ball 27 is matched with the size of the center sleeve 25, and the venting chamber 26 is arranged between the center sleeve 25 and the inner wall of the outer sleeve 24 for normal outward discharge operation of the gas; the guide chamber 251 is arranged in the center sleeve 25 and is connected with the outside, and the blocking ball 27 is slidingly connected with the guide chamber 251, thereby guiding the blocking ball 27 and avoiding the subsequent normal blocking of the conical sleeve 23.

[0029] In addition, the inner sheath 22 is fixedly installed at the bottom center position of the support disc 21, the inner sheath 22 is sleeved outside the tension spring 28, and the inner sheath 22 has the effect of protecting the tension spring 28 and avoiding deformation of the tension spring 28.

[0030] It is worth noting that the inner reinforcing sticker 29 is fixedly installed on the inner surface of the air chamber mattress body 1, and the outer reinforcing sticker 291 is fixedly installed on the outer surface of the air chamber mattress body 1, thereby achieving the effect of double reinforcement and fixation.

[0031] When the pressure in the air chamber mattress body 1 is too large, the gas pressure will push the blocking ball 27 outward, at this time, the blocking ball 27 no longer blocks the conical sleeve 23, and the gas in the air chamber mattress body 1 can be discharged outward along the vent hole 211, the conical sleeve 23, the venting chamber 26 and the exhaust hole 253, thereby achieving the pressure relief protection operation, and when the pressure in the air chamber mattress body 1 is reduced, the tension spring 28 can drive the blocking ball 27 to return to the original state, at this time, the blocking ball 27 continues to seal against the sealing pad layer 231 to achieve the effect of explosion-proof pressure relief protection.
