DETAILED DESCRIPTION

[0021] The utility model is further described below with the drawings and specific embodiments.

[0022] Refer to FIG. 1-FIG. 4, an airbag for the pillow with adjustable height, including: multiple airbag units (1) arranged in stack, an array of supporting and connecting holes 11 are oppositely set on the side of the airbag units (1); two adjacent airbag units (1) are connected through the supporting and connecting hole 11.

[0023] During the inflation or deflation of the airbag unit 1, the gas simultaneously flows into or out of the airbag from the multiple supporting and connecting holes 11, that the inflation rates of the respective parts of the airbag unit 1 relatively uniform, and the overall airbag height can be changed synchronously with the inflation or deflation.

[0024] Due to the use of stacked airbag units (1) to form one airbag, airbag units (1) communicate with each other through the array of supporting and connecting holes 11, during the inflation or deflation process of the airbag unit 1, the gas flows into or out of the airbag unit 1 from the multiple supporting and connecting holes 11 simultaneously, so that the various positions of the airbag unit 1 can be inflated or deflated at the same time, thus the air in each part of the airbag unit 1 is relatively uniform, so that the height change rate of all parts of the airbag unit 1 tend to be uniform during the inflation and deflation process.

[0025] In this embodiment, each airbag unit 1 has a strip extending along the longitudinal direction of the airbag, and the strip adheres the upper surface and the lower surface of the airbag unit 1 together, so that the airbag unit 1 forms multiple child-airbags 12 that communicate with each other. The child-airbag 12 extends in the longitudinal direction and is in communication with the other child-airbags 12 at both ends. In the present invention, there are three child-airbags 12, and each child-airbag 12 is provided with two supporting and connecting holes 11 in the longitudinal direction, such that one airbag unit 1 has 23 supporting and connecting holes 11. Such structure, on one hand, to reduce the area of the airbag unit 1 that needs to be inflated, so that the inflation and deflation processes are faster, and on the other hand, the airbag unit 1 is rendered highly uniform.

[0026] Since all the airbag units (1) are in communication with each other, it only needs to be provided with only one air intake nozzles 13 in one of the airbag units (1) to inflate all airbag units (1).

[0027] The intake nozzle 13 is provided at the side of the airbag unit 1. According to the needs of the structural settings, the air intake nozzle 13 can also be set at any other location, which is a simple changeable matter of this embodiment.

[0028] The lowermost airbag unit 1 has a connecting belt 2 for adhering the sponge on its lower surface, and the said connecting belt 2 is along the longitudinal direction of the airbag, and its both ends are respectively press-fitted to the airbag unit 1. The connecting belt 2 will not wrinkle by the inflation and deflation of the airbag, so that the connected sponge can also be kept flat at all times. Thus, the adhesion between the belt 2 and the sponge is relatively stable and does not come loose.

[0029] Through testing, in this design, an airbag with a flattened area of 5023 cm can be adjusted to a height of 7.5 cm in about 1 minute and 10 seconds using a given air pump. Using the same air pump, a single-layer airbag takes at least 8 minutes to reach the same height. Therefore, this design greatly reduced the waiting time and power consumption.

[0030] The utility model also provides a pillow with adjustable height using such airbag as described above.

[0031] The above is only some preferred embodiments of the utility model, but the scope of the utility model is not limited thereto, the disclosed variations or technical scopes of this utility model can be easily conceived by the technical personnel in this field. Alternative plans are intended to be included within the scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the Claims.
