Abstract

An inflatable bedding includes an inflatable component (10), and the inflatable component (10) includes an inflatable air chamber (100) and an air nozzle (101). A top surface layer (21) is connected to the inflatable component (10). A padding chamber (200) is formed between the top surface layer (21) and an outer surface of the inflatable component (10). The padding chamber (200) is filled with a padding (22). The padding (22) is connected to the top surface layer (21) to form a connection region (A). The connection region (A) is configured to allow air to enter or exit the padding chamber (200) therethrough. With the formation of the region allowing air to enter or exit the padding chamber (200) on the top surface layer (21), the padding chamber (200) can be directly inflated or deflated through the top surface layer (21), so that the inflation and deflation efficiency is improved. The fixed connection of the padding (22) inside the padding chamber (200) can prevent the padding (22) from moving in the padding chamber (200), thereby providing improved comfort during use.

Description

TECHNICAL FIELD The present invention relates to an inflatable product, and specifically to an inflatable bedding. BACKGROUND In daily life, inflatable bedding can be used as pillows, mattresses, seat cushions, back cushions, etc. At present, inflatable bedding is generally classified into the following types by the structure. A first type of inflatable bedding includes an outer shell formed by sealed joining of a flexible air impermeable material and defining a chamber. An air nozzle in communication with the chamber is provided on the outer shell. The hardness of the inflatable bedding is determined by the amount of inflation. If the inflation is too much, the inflatable bedding will be too hard to fit a human body. If the inflation is too little, the inflatable bedding cannot provide sufficient support. Because the amount of inflation is not easy to adjust, this type of inflatable bedding cannot provide sufficient comfort. A second type of inflatable bedding includes an outer shell formed by sealed joining of a flexible air impermeable material and defining a chamber, and a padding in the chamber. The padding is generally made of sponge or hollow cotton. The padding has a predetermined volume in order to meet the requirements on the height and comfort of the inflatable bedding. Therefore, this type of inflatable bedding requires much space for storage even after deflation. A third type of inflatable bedding is a combination of an inflatable bedding of the first type and an inflatable bedding of the second type. An inflatable air chamber is provided in the lower part of the inflatable bedding of the second type. Although such a structure provides greater comfort than the first type of inflatable bedding and requires less sponge than the second type of inflatable bedding under the same pillow height, two air nozzles need to be provided, making it troublesome to inflate and deflate. SUMMARY An objective of the present invention is to provide an inflatable bedding which is easy to store and has high inflation and deflation efficiency.
