第３気室２３に接続されている。 The feature of the present invention lies in the structure of the air supply mechanism 20, in which a first pump 21 and a second pump 22 are disposed.
A distributor 24, which will be described later, is connected via a pressure control valve 23 to a pipe 26. On the other hand, a flow control valve 25 is connected to the second pump 22 . Here, the first and second pumps 21 and 22 are appropriate pressurized air pumps or compressors, such as a rotary type or a reciprocating type. Also, two pipes 27 and 28 coming out from the distributor 24 are connected to the first air chamber 11 and the second air chamber 11, respectively.
A flow control valve 25 connected to the air chamber 12 and connected to the second pump 22 is connected to the third air chamber 23 by a pipe 29.

圧空気が流入する。 For example, a pressure reducing valve or a relief valve is used as the pressure control valve 23. When using a pressure reducing valve, the set pressure can be changed by turning the handle, and the balance between the pressure in the diaphragm chamber and the elastic force of the spring that presses the diaphragm is adjusted, and the pressure on the primary side is adjusted. and pressurized air flows into the secondary side,
When the diaphragm chamber is pressurized by the air flowing to the secondary side, when the pressure within the chamber reaches equilibrium with the elastic force of the spring, the valve is closed to prevent air from flowing into the secondary side. When the action is performed and the pressure in the diaphragm chamber decreases, the valve closes again and pressurized air flows into the secondary side.

行なうことができる。 For example, a throttle valve is used as the flow rate control valve 25. This throttle valve uses a mechanically operated throttle valve that mechanically changes the area of the air passage inside the valve when the air pressure exceeds a predetermined value, and an exhaust valve that changes the flow rate of air discharged from the exhaust port by adjusting a screw-in throttle mechanism. A throttle valve is used, and as the opening of the throttle section increases, the flow rate increases. Further, the adjustment can be made manually.

えることがないという効果もある。(Effect of the invention) The present invention supplies pressurized air to the third air chamber by a second pump that is separate from the pump for generating wave motion, and controls the flow rate by using a flow rate control valve. For example, 1
Compared to a conventional device that uses a single pump and controls the pressurized air supplied from the pump with a solenoid valve that operates according to the operation of a changeover switch,
The air for drying the skin is ejected regardless of the wave motion, and an appropriate flow rate of air can be ejected. Therefore, according to the present invention, the air ejected from the upper surface of the air mattress body can be adjusted according to the physical condition and preferences of the person sleeping on the air mattress body and then ejected from the air outlet, thereby preventing bedsores from conventional bedsore prevention. Unlike other devices, we carefully consider the body temperature of a sleeping patient, etc.
For example, excessive air blowout can be prevented. Furthermore, in this invention, by adjusting the air flow rate, the third air chamber can be maintained in a constantly inflated state with almost no air being ejected from the air outlet, so the first air chamber and the second air chamber are alternately activated at one time. It also has the effect of not causing anxiety to the sick person even when it contracts.
