Description

Technical Field

[0001] This application belongs to the field of pillow devices, and specifically relates to a multi-airbag pillow assembly with pressure detection and a multi-airbag pressure detection pillow. Background Technology

[0002] The simplest airbag pillows in the current technology are mostly in the form of a single airbag, and the inflation and deflation control process is relatively simple.

[0003] As the demand for pillows increases, the ability to control and adjust pillow height and perform functions such as anti-snoring requires precise control over the state of the airbag.

[0004] Existing anti-snoring pillows often feature multiple airbags, but the control mechanisms for these airbags are relatively simple, typically relying on external pressure sensors to detect airbag pressure. However, due to variations in airbag material and inflation states, the internal pressure measurement of the airbags is inaccurate. This inaccuracy can affect subsequent control mechanisms and negatively impact the user experience.

[0005] like Figure 9 This is the connection method in the existing technology. The coordinated control of multiple airbags is complex and it is difficult to accurately control the pressure of a single airbag.
