Pillow and method for detecting head position through Hall sensing devices

Abstract

The invention provides a pillow and method for detecting the head position through Hall sensing devices. The pillow comprises a pillow inner and a plurality of Hall sensing assemblies and a controller which are arranged in the pillow inner; each Hall sensing assembly comprises a Hall sensor and a magnet which are correspondingly arranged in the same vertical direction, an elastic separation distance is formed between each Hall sensor and the corresponding magnet and changes under the head pressure action, the Hall sensors are connected with the controller, and the controller detects the head position according to the output analog quantity of the Hall sensors. According to the pillow, the sensing mode that the Hall sensors are adopted to cooperate with the magnets is sensitive and accurate, the heads of users with the different weights all can enable the elastic separation distances to change, and the Hall sensors can sense changes of the magnetic field intensity. Accordingly, the problem that the detection accuracy is influenced by the different weights of the users is solved, and the advantages of being capable of being applied to the users with the different weights, accurate in detection and wide in applicability are achieved.

Description

technical field [0001] The invention relates to the technical field of health pillows, in particular to a pillow and a method for detecting the position of a head by using a Hall sensor device. Background technique [0002] Along with the raising and progress of living standard, the single function that common pillow is used for sleeping can't satisfy people's ever-changing needs. There are more and more smart pillows and functional pillows on the market, such as intelligent adjustable pillows that automatically adjust the height of the pillow, intelligent monitoring pillows that can monitor the user's sleep quality, and anti-snoring pillows that can help users stop snoring, etc. . These smart pillows and functional pillows need to judge the position of the head before realizing their functions. If the position of the head cannot be judged more accurately, it will be difficult for the smart, massage, and anti-snoring mechanisms on the headrest to intervene at precise posit...

AI Technical Summary

Problems solved by technology

However, the detection process of this scheme will be easily affected by the weight of the user. The weight of the user is different, and the pressure generated by the head resting on the pillow is also different.

Membrane switches are difficult to apply to all users of different weights, and it is very easy to cause misjudgment or missed judgment of the head position, which will also directly affect the implementation and implementation effect of smart, massage and other functions
