Embodiment 3

(29) Referring to FIG. 9, the present embodiment differs from Embodiment 2 in that: the second pull strap 8 is not defined with the second through hole 81, and is also not of the mesh pull strap structure. Specifically, a PVC sheet pull strap surrounds the side wall of the pillow mat 7, and the second pull strap 8 is provided with at least one one-way air nozzle 9, and the one-way air nozzle 9 with a common structure of the one-way air nozzle 9 in the market; correspondingly, referring to FIG. 10, the bottom sheet 2 is provided with an air inlet nozzle 21 corresponding to a position of the pillow mat 7.

(30) As shown in detail in FIGS. 11-12, the one-way air nozzle 9 includes a connecting seat 91 and a one-way diaphragm 92, an outer wall of the connecting seat 91 is provided with a connecting ring 94 arranged in a circumferential direction of the connecting seat 91.

A connecting column 921 is provided on one surface of the one-way diaphragm 92, specifically, the connecting column 921 is provided on one surface of the one-way diaphragm 92 close to the pillow mat 7, preferably, the connecting column 921 is integrally connected and formed with the one-way diaphragm 92, and is preferably made of soft rubber. Further, a middle of the connecting column 921 is defined with an annular clamping groove 922 along a circumferential direction thereof, so that the top of the connecting column 921 can pass through the connecting hole 931 by being slightly deformed, so that the annular clamping groove 922 is clamped in the connecting hole 931. The end portion of the connecting column 921 is limited to one surface of the connecting disc 93 close to the pillow mat 7, and an axial length of the annular clamping groove 922 is greater than a thickness of the connecting disc 93, so that a part of the connecting column 921 corresponding to the annular clamping groove 922 can move relatively in the connecting hole 931. When the one-way diaphragm 92 abuts against the connecting disc 93, the one-way diaphragm 92 seals the plurality of vents 932, so that the gas cannot flow from a surface of the connecting disc 93 away from the pillow mat 7 to a surface of the connecting disc 93 close to the pillow mat 7; when the one-way diaphragm 92 moves 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 facilitate a flow of 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, and then into the air chamber 100.

(32) Referring to FIGS. 11 and 13, the side enclosing sheet 3 of the present embodiment is provided with the air pumping integrated device 51 or the inflating and deflating air nozzle 52, or as shown in FIG. 14, the side enclosing sheet 3 is provided with the air pumping integrated device 51 and the inflating and deflating air nozzle 52 at the same time. When the air pumping integrated device 51 and the inflating and deflating air nozzle 52 are provided at the same time, the air pumping integrated device 51 and the inflating and deflating air nozzle 52 can be provided on the same side wall or different side walls of the side enclosing sheet 3, and both of which are within the scope of protection of the present application.

(33) The implementation principle of embodiment 3 is: the one-way air nozzle 9 is firstly fixed on the second pull strap 8, and then the second pull strap 8 is arranged around the side wall of the pillow mat 7, in particular, one face of the one-way diaphragm 92 provided with a connecting column 821 is arranged towards the pillow mat 7.

(34) The process of connecting the top sheet 1, the bottom sheet 2, the side enclosing sheet 3, the bed mat 4, the first pull strap 6, the pillow mat 7 and the second pull strap 8 to prepare the inflatable sponge mat is the same as in Embodiment 2, and the description thereof will not be repeated here.

(35) When the inflatable sponge mat needs to be used, performing inflation into the air chamber 100 by connecting the inflating and deflating air nozzle 52 with the external air pumping device or directly through the inflation function of the air pumping integrated device 51; alternatively, performing inflation by connecting the external air pumping device with the inflating and deflating air nozzle 52, as well as through the inflation function of the air pumping integrated device 51. During the process of inflating the air chamber 100 by the air pumping integrated device 51 and/or the inflating and deflating air nozzle 52, a self-inflation and deflation can be achieved by stepping on the pillow mat 7 to further improve the inflation efficiency.

(36) 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.

(37) 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.

(38) 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.

(39) What is provided above is merely the preferred embodiments according to the present application, and the protection scope of the present application is not limited to the above embodiments. 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.
