Structure of automatic pressure adjustable air bed

Abstract

An improved structure of automatic pressure adjustable air bed mainly includes an air mattress, an air pump, and air pipes arranged therebetween, as well as a control system disposed on the air bed. The control system includes multiple pressure sensors disposed on the air mattress for acquiring pressure signals, and a main control unit for controlling actions of the air pump or electrical controlled valves thereon, thereby achieving the automatic adjustment of firmness of the air mattress.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of Invention[0002]The present invention relates to an improved structure of automatic pressure adjustable air bed, in particular, to an air bed structure dedicated for bedridden patients, in which a control system for automatically controlling the air-charging pressure of the mattress is disposed, so as to achieve the automatic adjustment of the firmness of the air mattress.[0003]2. Related Art[0004]A conventional air bed structure mainly includes an air mattress, an air pump, and an air pipe arranged therebetween. The air mattress is divided into multiple air inflation areas, such as three areas for head, body, and feet (or more areas). The air pump is activated to charge air into and pressurize different areas of the air mattress via the air pipe at the same time, so as to achieve the purpose of air charging.[0005]However, for the conventional air bed structure in use, the air pump is controlled to activate or shut down manually. When the ...

Benefits of technology

[0008]The present invention is directed to an improved structure of automatic pressure adjustable air bed, capable of automatically detecting and adjusting the air pressure of an air mattress, thereby reducing the labor burden and providing an air bed with moderate firmness and more comfortable experience for users.

[0010]Based on the above structure combination in use, if a person is lying on the air mattress of the air bed, after the system is powered on, the system senses the pressures by the use of the pressure sensors disposed on the air inflation area of the air mattress, and respectively generates a pressure signal transmitted to the control unit. After receiving the signals, the main control unit respectively generates corresponding control signals to the air pump and / or multiple electrical controlled valves, so as to activate the air pump and / or multiple electrical controlled valves to charge air if the air-charging is needed or exhaust air if the pressure-relief is required, thereby achieving the automatic adjustment of the firmness of the air mattress.

Problems solved by technology

It is difficult to use a single air pump to charge multiple areas bearing different weights to achieve proper air pressure in all areas, so other control devices or structures must be used.

In addition, bedridden patients mostly lose their moving or speaking ability, and cannot operate the pressure adjusting device or structure at will, so they need an assistant.

Therefore, in addition to the demands for human resources and the cost, it is uneasy to make accurate adjustment to achieve the proper firmness.
