When the capacitance values of the strip-shaped capacitive sensors 26 are different, it indicates that the influence of the human body on the capacitance values of the strip-shaped capacitive sensors 26 is different, for example, the human body may form a medium between two electrode plates of the strip-shaped capacitive sensors 26, thereby influencing the dielectric constant between the electrode plates. Different parts of the human body lie on different strip-shaped capacitive sensors 26, so that different capacitance value distributions are formed.

By paving the plurality of strip-shaped capacitive sensors 26 on the mattress body 21, when a human body lies on the mattress body 21, the strip-shaped capacitive sensors 26 can generate capacitance values, and different strip-shaped capacitive sensors 26 can generate different capacitance values due to corresponding to different human body parts, and the trend change of the human body width along the length direction of the bed body can be judged through the change of the capacitance values. In addition, the sensing of the strip-shaped capacitive sensor 26 to the capacitance value does not require how much pressure the human body needs to generate on the strip-shaped capacitive sensor 26, so that the sensing error caused by different pressures generated by direct contact between certain parts of different human bodies and the bed body can be avoided, and the recognition error of the parts of the human body can be avoided.

Therefore, the capacitance value generated by the strip-shaped capacitive sensor 26 at the waist position is smaller than that generated by the strip-shaped capacitive sensor 26 at the back position and the hip position, so that the positions of the human body can be judged according to the capacitance values of the different strip-shaped capacitive sensors 26, and accurate massage of the human body is realized.

In this embodiment, a music vibrator 7 may be further installed at the position of the lower leg of the mattress body 21 to massage the lower leg. The head part of the mattress body 21 can be provided with a loudspeaker, and the loudspeaker is suitable for playing music, especially for playing sleep-assisting music. Mattress body 21 is last can also to integrate and help the dormancy lamp area, help the dormancy lamp area can send and help dormancy light.

Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Various changes and modifications may be effected therein by one of ordinary skill in the pertinent art without departing from the spirit and scope of the present disclosure, and these changes and modifications are intended to be within the scope of the present disclosure.
