Description

CROSS-REFERENCE TO RELATED APPLICATION

The present application claims the priority and benefit of Chinese patent application No. 202422148880.9, filed on Sep. 2, 2024. The entirety of Chinese patent application No. 202422148880.9 is hereby incorporated by reference herein and made a part of this specification.

TECHNICAL FIELD

The present application relates to a field of inflatable mats, and more particularly to an inflatable sponge mat.

BACKGROUND ART

Because of its portability and easy storage, an inflatable mattress is popular in outdoor activities and domestic use. At present, most sleeping mats on the market are inflatable, and a closed air chamber is formed by sealing and connecting a top sheet, a bottom sheet and a side enclosing sheet to realize an inflatable function of a mattress. The inflatable mattress can be used after being fully inflated, but traditional inflatable mattresses often cause an imbalance in internal pressure due to uneven weight distribution or body movement during long-term use, resulting in a deformation of the mattress and affecting a comfort of use.

In this regard, an internal air column structure or a plurality of wire-drawn structures provided with a grid layout mode are currently used on the market to improve a support force of the mattress, but the internal air column structure is also by inflating or deflating to adjust a support of the mattress, which is also easy to cause uneven local pressure of the mattress due to uneven weight distribution or body movement during use. Meanwhile, after the mattress is inflated, the wire-drawn structure will pull a connection with the top sheet and the bottom sheet inwards, so that a plurality of concave connection point locations appear on a surface of the mattress, reducing a flatness and comfort of a sleeping area of the mattress.

SUMMARY

In order to solve a problem of support stability of the inflatable mattress, the present application provides an inflatable sponge mat.

The inflatable sponge mat provided in the present application adopts the following technical solution.

An inflatable sponge mat including a top sheet, a bottom sheet, a side enclosing sheet and a bed mat, wherein four edges of the top sheet is connected to a top of the side enclosing sheet, four edges of the bottom sheet is connected to a bottom of the side enclosing sheet; the top sheet, the bottom sheet and the side enclosing sheet enclose to form an air chamber, the bed mat is arranged in the air chamber, an upper surface of the bed mat is fixedly connected to a lower surface of the top sheet, and a lower surface of the bed mat is fixedly connected to an upper surface of the bottom sheet; the side enclosing sheet is provided with an air pumping assembly.

By adopting the above-mentioned technical solution, the bed mat provides a stable supporting force and comfort for a bed, and a fixed connection of the bed mat with the top sheet and the bottom sheet can increase a stability of the bed mat and prevent the bed mat from shifting or folding during use.

On the other hand, at present, in autumn and winter or in northern regions with higher latitudes, there is a colder skin feel when using inflatable beds, which reduces the comfort of use. In this regard, the present application uses a bed mat with better thermal insulation performance to reduce a heat conduction and diffusion of the bed and improve the comfort of using the inflatable sponge mat.

In some embodiments, the inflatable sponge mat further includes a first pull strap, wherein the first pull strap surrounds a side wall of the bed mat, a top of the first pull strap is connected to the top sheet, and a bottom of the first pull strap is connected to the bottom sheet.

By adopting the above-mentioned technical solution, a surrounding arrangement of the first pull strap on the bed mat can effectively prevent a deformation or displacement of the bed mat caused by pressure or movement during use, and ensure the stability and comfort of the bed mat.

In some embodiments, the first pull strap is defined with a plurality of first through holes.

In some embodiments, the first pull strap is a mesh pull strap.

By adopting the above-mentioned technical solution, while ensuring a strength of the first pull strap, an overall weight of the first pull strap can be reduced and a gas permeability can be improved. On one hand, the mesh pull strap can ensure that a user can keep dry and comfortable in a hot or sweaty environment, and on the other hand, the mesh pull strap can ensure that when the air chamber is inflated, a gas filled can enter micropores of the bed mat through the first through hole or meshes of the mesh pull strap to ensure the support stability and comfort of the bed mat.

In some embodiments, a height of the first pull strap is less than that of the bed mat.

By adopting the above-mentioned technical solution, when the inflatable sponge mat is inflated for use, the first pull strap pulls the top sheet and the bottom sheet inwards, thereby enabling the top sheet, the bottom sheet and the first pull strap to wrap around the bed mat stably, which prevents the bed mat from being easily displaced or deformed due to pressure during use, thereby ensuring the support stability of the bed mat.

In some embodiments, the air pumping assembly is an air pumping integrated device and/or an inflating and deflating air nozzle.

By adopting the above-mentioned technical solution, an operation of inflating and deflating the air chamber is diversified to adapt to requirements of different use scenarios; for example, the air pumping integrated device can realize an integration of inflation and deflation; by arranging the inflating and deflating air nozzle, other separate external inflation and deflation integrated pumps can be used in connection with the inflating and deflating air nozzle to perform an inflation or deflation operation on the air chamber; the air pumping integrated device and the inflating and deflating air nozzle can also be arranged at the same time to make the inflation or deflation operation diversified.

In some embodiments, the inflatable sponge mat further includes a pillow mat, wherein the pillow mat is arranged in the air chamber and close to one end of the top sheet; an upper surface of the pillow mat is fixedly connected to the lower surface of the top sheet and a lower surface of the pillow mat is fixedly connected to the upper surface of the bottom sheet.

By adopting the above-mentioned technical solution, an integrated design of the pillow mat and the bed mat can be realized, saving a trouble of carrying an additional pillow, reducing a travel load, suitable for outdoor camping or temporary rest and other scenarios, improving a convenience of using the inflatable sponge mat and providing a stable supporting force for the inflatable sponge mat. In addition, the pillow mat is also fixedly connected to the top sheet and the bottom sheet to avoid deformation or displacement caused by pressure or movement during use, and is comfortable to use.

In some embodiments, the inflatable sponge mat further includes a second pull strap, wherein the second pull strap surrounds a side wall of the pillow mat, a top of the second pull strap is connected to the top sheet, and a bottom of the second pull strap is connected to the bottom sheet.

In the present application, an effect of the second pull strap is similar to the first pull strap.

In some embodiments, the second pull strap is defined with a plurality of second through holes.

In some embodiments, the second pull strap is the mesh pull strap.

In some embodiments, the second pull strap is provided with at least one one-way air nozzle, and the bottom sheet is provided with an air inlet nozzle at a position corresponding to the pillow mat, and the one-way air nozzle is used for limiting a gas from flowing only from the pillow mat into the air chamber.

By adopting the above-mentioned technical solution, an additional inflation method can be provided for the inflatable sponge mat to improve an inflation efficiency, and the one-way air nozzle is provided inside the air chamber, and the integrated design can reduce a foreign body sensation of accessories to a human body during use and make the use comfortable. Specifically, an elastic force of the pillow mat provides a compression and rebound function, and the micropores of the pillow mat can contain gas, and when the pillow mat is compressed, the gas in the micropores of the pillow mat flows into the air chamber through the one-way air nozzle; when the pillow mat rebounds to an original state, a volume of the micropores of the pillow mat are compressed and a negative pressure is formed in the micropores during a process of returning the original state, which sucks in external air from the air inlet nozzle into the pillow mat, and the negative pressure of the micropores of the pillow mat also seals the one-way air nozzle, so that when the pillow mat returns to the original state to suck air, no air is input into the air chamber, thereby using a compression resilience of the pillow mat to inflate the air chamber.

In some embodiments, the one-way air nozzle includes a connecting seat and a one-way diaphragm, a through hole is defined in a middle of the connecting seat, the through hole penetrates through both surfaces of the connecting seat, and a connecting disc is provided on a hole wall of the connecting seat corresponding to the through hole, the connecting disc is defined with a connecting hole and a plurality of vents, and the one-way diaphragm covers the plurality of vents;

the one-way diaphragm is provided with a connecting column on one surface close to the pillow mat, a middle of the connecting column is defined with an annular clamping groove along a circumferential direction thereof, the connecting column passes through the connecting hole, and the annular clamping groove is clamped in the connecting hole.

By adopting the above-mentioned technical solution, a one-way flow of gas from the pillow mat to the air chamber can be realized, so that the inflation operation of the inflatable sponge mat is facilitated and the use thereof is convenient. Specifically, the one-way diaphragm is connected to the connecting disc through the connecting column and the annular clamping groove; when the pillow mat is compressed, the volume of the micropores of the pillow mat decreases and an air pressure increases, which causes the one-way diaphragm to separate from the bottom of the connecting disc and form a certain gap; the one-way diaphragm releases the seal against the vent;

the annular clamping groove remains clamped in the connecting hole; an end of the connecting column is limited to one side of the connecting disc close to the pillow mat, facilitating a flow of gas from the micropores of the pillow mat into the air chamber. However, when the compression of the pillow mat is released, the elastic force of the pillow mat itself promotes the pillow mat to return the original state, the volume of the micropores of the compressed pillow mat increases and the air pressure decreases, which causes the one-way diaphragm to press against the bottom of the connecting disc, and the connecting hole and a plurality of vents are sealed. At the same time, the negative pressure thereof promotes an outside air to enter the pillow mat through the air inlet nozzle, so that the pillow mat itself completes the inflation of the micropores.

In some embodiments, an axial length of the annular clamping groove is greater than a thickness of the connecting disc.

By adopting the above-mentioned technical solution, a certain gap space can be provided between the one-way diaphragm and the bottom of the connecting disc; when the pillow mat is compressed, the one-way diaphragm is separated from the bottom of the connecting disc, and the seal against the vent is released; and the end of the connecting column is limited at the side of the connecting disc close to the pillow mat, and the gas in the micropores of the pillow mat can flow into the air chamber through the vent and the gap space, which is flexible and convenient to use.

In some embodiments, an outer wall of the connecting seat is provided with a connecting ring along a circumferential direction thereof, and the connecting ring is fixedly connected to the second pull strap.

By adopting the above-mentioned technical solution, a connection stability between the one-way air nozzle and the second pull strap can be improved, an installation process of the one-way air nozzle is simplified, and a production efficiency of products is improved.

In some embodiments, a height of the second pull strap is less than that of the pillow mat.

In summary, the present application includes at least one of the following beneficial technical effects.

• • 1. In the present application, the air chamber is formed by surrounding the top sheet, the bottom sheet and the side enclosing sheet, and a bed mat is provided inside, wherein the bed mat provides stable support and comfort in use, so that the inflatable sponge mat is convenient to carry and has good comfort. During use, the bed is not easy to deform or partially collapse due to uneven pressure, and the thermal insulation performance of the bed mat also enables the inflatable sponge mat suitable for autumn and winter seasons, with high practicality.

When the pillow mat 7 is stepped on by a foot, the pillow mat 7 is compressed, the volume of the micropores of the pillow mat 7 is reduced, and when a gas pressure in the micropores presses the one-way diaphragm 92 away from the connecting disc 93, the one-way diaphragm 92 unseals the vent 932 such that there is a gap between the connecting disc 93 and the one-way diaphragm 92, which facilitates the flow gas from the surface of the connecting disc 93 close to the pillow mat 7 to the surface of the connecting disc 93 away from the pillow mat 7, then into the air chamber 100. When the compression of the pillow mat 7 is released, the pillow mat 7 returns to an original state due to an own resilience of the pillow mat 7, and a negative pressure is formed in the micropores during the process of returning to the original state, and external air is sucked from the air inlet nozzle 21 into the micropores of the pillow mat 7, and the negative pressure of the micropores of the pillow mat 7 also enables the one-way diaphragm 92 to abut against the connecting disc 93 and seal the vent 932, so that when the pillow mat 7 returns to the original state to suck air, no air is input into the air chamber 100. Such is a self-compressed inflation to an air chamber, a self-resilience air suck to a pillow mat 7 process that is accomplished using the compression resilience of the pillow mat 7.

The inflated air can uniformly flow into the air chamber 100 and enter the micropores of the bed mat 4 through the first through holes 61 or meshes of the first pull strap 6 to realize the inflation process.

When there is no need to use the inflatable sponge mat, the air in the air chamber 100 is deflated and discharged through the inflating and deflating air nozzle 52, and when being stored, the air in the air chamber 100, the air in the micropores of the bed mat 4, the air in the micropores of the pillow mat 7 can be squeezed while being rolled up, achieving exhaust storage. In addition, it can also be connected the inflating and deflating air nozzle 52 to the external air pumping device, or directly use the air pumping function of the air pumping integrated device 51 to accelerate the extraction of the air in the air chamber 100 to the outside to facilitate the folding and rolling of the inflatable sponge mat, and the volume of the inflatable sponge mat after the folding and rolling is smaller.

Therefore, any equivalent changes made based on the structure, shape, or principle of the present application should be encompassed within the scope of protection of the present application.
