[0061] Specifically, the pressure data is a pressure image of the human body on the bed body, and one time point corresponds to one pressure image; in the actual detection process, the pressure sensor 61 on the bed body continuously detects the pressure on the bed body over time, and in one time point, the pressure value greater than the pressure threshold data is extracted from the pressure data detected at the time point to obtain the pressure image corresponding to the time point, the pressure image includes a plurality of pressure regions, the largest pressure region is selected, and the feature value is extracted from the pressure region according to the measured pressure data, and then the human sleep posture is determined according to the extracted feature value according to the judgment flow to obtain the sleep posture detection result; and the pressure data detected at the next time point is extracted again, the feature value is extracted, and the sleep posture is determined, that is, one pressure image is acquired at one time point, and then the feature value is extracted according to the pressure image, and the sleep posture at the time point is determined. The pressure threshold data is 15-25g, preferably 20g.

[0062] It should be noted that the technical content of determining the sleep posture detection result based on the pressure data of the pressure sensor 61 is prior art, and the specific content can be referred to the patent documents with publication numbers CN111000528A and CN116563940A, which will not be described in detail here.

The three image acquisition devices 62 acquire the upper human sleep posture image data, the left human sleep posture image data and the right human sleep posture image data respectively, and transmit them to the second control processor; the second control processor pre-processes, extracts and identifies the upper human sleep posture image data, the left human sleep posture image data and the right human sleep posture image data, so as to acquire the corresponding human sleep posture image feature value group; and finally confirms the sleep posture detection result according to the human sleep posture image feature value group.

[0065] Specifically, the three image acquisition devices 62 are arranged on the headboard 13, the first side guardrail 11, and the second side guardrail 12 respectively.

[0066] It should be noted that the technical content of determining the sleep posture detection result by the image data of the image acquisition device 62 is prior art, and the specific content can be referred to the patent documents with publication numbers CN114698975A and CN114998229A, which will not be described in detail here.

[0076] In some specific embodiments, the control module is configured to selectively adjust the air outlet parameter of the main air outlet 51 based on the sleep posture detection result of the sleep posture detection module. Specifically, when the sleep posture detection result of the sleep posture detection module is left lateral position or right lateral position, the control module increases the air volume value and / or the air speed value of the main air outlet 51; wherein adjusting the air volume value and the air speed value of the main air outlet 51 can be realized by controlling the air volume and the air speed of the main air fan or the main air valve 54. Through the above arrangement, it is avoided to adjust the opening and closing state and / or the air outlet parameter of the first side air outlet 31 and the second side air outlet 41 to affect the air purification effect of the sickbed, so as to ensure that the air purification effect of the sickbed will not be reduced.

[0077] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings, but those skilled in the art can easily understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after the changes or replacements will fall within the protection scope of the present application.
