Description

Technical Field

[0001] The invention relates to the technical field of household products, and more particularly to a height-adjustable smart pillow. Background Art

[0002] When people sleep, they generally need a pillow of appropriate height to cushion the neck to maintain the normal physiological curve of the human body and ensure that the physiological curvature of the neck does not deform during sleep. A pillow that is too high or too low can easily cause a stiff neck after getting up, with obvious soreness in the neck and back and difficulty in neck movement. A pillow that is too low can also easily cause dry mouth, dry tongue, sore throat, snoring, etc. Since many people often want a higher pillow before sleeping so that they can watch TV, read books, or play with mobile phones in bed, but if they continue to use a pillow that is too high after falling asleep, it is easy to cause a stiff neck. Therefore, a pillow technology solution that can automatically adjust the height after a person falls asleep has emerged.

[0003] The height-adjustable pillow disclosed in Chinese Patent No. 200620044906.4 is a technical solution for a pillow that can automatically adjust its height after a person falls asleep. Its structure includes a pillowcase, the pillowcase is combined with an inflatable pillow core, one end of the air valve is connected to the inflatable pillow core, and the other end of the air valve is connected to the atmosphere. The air valve is combined with a timer and forms a timing air valve with the timer, and the inflatable pillow core has an air intake mechanism. The height of the pillow can be adjusted by electric inflation and deflation, and the pillow height can be lowered by deflation after a person falls asleep by setting a timer.

[0004] The defects of this technical solution are: first, the degree of increase and decrease of the pillow height cannot be pre-set, which brings inconvenience to the use, especially after the person falls asleep, he cannot sense and adjust the height of the pillow, which will cause the pillow to deflate and lower after falling asleep and the height will be inappropriate; second, when using existing pillows, different heights of needles are selected for different groups of people, but for some people with breathing disorders, the pillow sometimes needs to be high and sometimes needs to be low, which is not convenient for fine-tuning the height. Summary of the invention
