[0053] A mattress frame is used to accommodate and fix the air mattress and the inflation and deflation device.

[0054] Specifically, the mattress frame includes a support plate 31 and an enclosure structure 32, the support plate 31 and the enclosure structure 32 enclose a chamber, the air cushion 1 is installed in the chamber, the upper surface of the air cushion is flush with the upper surface of the enclosure structure 32, the inflation and deflation device 2 is installed in the chamber near the end of the bed, and the inflation and deflation device 2 is filled with sound insulation sponge. A first sponge layer 33 is provided between the support plate 31 and the air cushion 2, and a second sponge layer 34 is laid on the air cushion 2. The support plate 31 in this embodiment is made of brown board, and the enclosure structure 32 is composed of shaped sponges.

[0055] The air cushion is provided with two air bags, which are distributed on the left and right sides. The two air bags are respectively provided with an inflation and deflation valve 13, which is connected to the inflation and deflation device. The control element is respectively electrically connected to the inflation and deflation valve 13 and the inflation and deflation device so that the control element can respectively control the inflation and deflation of the two air cushions. Thus, the two sides of the air cushion can be adjusted to different hardness (i.e., the air pressure in the air cushion is different) to meet the different softness and hardness requirements of two people on the double bed.

[0056] Specifically, the inflation and deflation device includes an inflation pump 21, an inflation tube 22 and a solenoid valve (the solenoid valve is not shown in the figure, connecting the inflation tube with the outside air, and when opened, the gas in the inflation cavity can be discharged through the inflation tube).

[0059] Example 2

[0060] An intelligent control method for an intelligent mattress, the intelligent control method is applied to the intelligent mattress in Example 1, including a manual adjustment mode and an automatic adjustment mode.

[0061] Manual mode:

[0062] S1 The user selects one of the several preset air pressure values ​​P1 in the control element. At this time, the air pressure sensor detects the air pressure in the inflation cavity in real time and transmits the real-time air pressure value P2 to the control element. The control element compares the real-time air pressure value with the selected air pressure value P1;

[0063] If the real-time air pressure value P2 is less than the selected air pressure value P1, the control element controls the air pump to inflate the air chamber. At this time, the working power of the air pump is 100%, so as to quickly inflate the air cushion so that the air pressure quickly reaches the predetermined air pressure value. When the real-time air pressure value P2 is equal to the selected air pressure value P1, the air pump is turned off to stop inflating, the manual mode is completed and the automatic mode is started;

[0064] If the real-time air pressure value P2 is greater than the selected air pressure value P1, the control element controls the solenoid valve to open, so that the inflation chamber is deflated, until the real-time air pressure value P2 is equal to the selected air pressure value P1, the solenoid valve is closed to stop deflation, the manual mode is completed and the automatic mode is started;

[0065] Automatic mode:

[0066] S2 detects the air pressure value P2 in the inflation chamber every 1s-5min.

[0067] If P1-P2≥0.2KPa and Pn is maintained for 10-20min (15min in this embodiment), the control element controls the air pump to inflate the air chamber. At this time, the working power of the air pump is 10%-60% to reduce noise. When the real-time air pressure value P2 is equal to the selected air pressure value P1, the air pump is turned off to stop inflation.

[0068] If P2-P1≥0.2KPa and Pn is maintained for 10-20min, the control element controls the solenoid valve to open, so that the inflation chamber is deflated until the real-time air pressure value P2 is equal to the selected air pressure value P1, and then the solenoid valve is closed to stop deflation;

[0069] Setting P1-P2 ≥ 0.2KPa or P2-P1 ≥ 0.2KPa to start automatic inflation and deflation can prevent the normal activities of the person on the bed from causing the air pressure in the air cushion to change and cause continuous inflation and deflation. Continuous adjustment of the air pressure will affect the normal rest of the person on the bed.

[0070] S3 When the user reselects the preset air pressure value P1+, the control element replaces P1 in step S1 and step S2 with P1+ and repeats step S1 and step S2.

[0071] Among them, P1 or P1+ can be selected from 2KPa, 2.5KPa, 3KPa, 3.5KPa, 4KPa, 4.5KPa, 5KPa, 6KPa, and 14KPa.

[0072] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
