A pid-controlled anti-snoring smart pillow

Abstract

The invention discloses a PID-controlled snore stopping intelligent pillow which comprises a pillow body. A left air chamber and a right air chamber are arranged inside the pillow body. A left air bag, a first exhaust pipe and a first inflation pipe are arranged inside the left air chamber. The first exhaust pipe and the first inflation pipe are communicated with the left air bag separately. A right air bag, a second exhaust pipe and a second inflation pipe are arranged inside the right air chamber. The second exhaust pipe and the second inflation pipe are communicated with the right air bag separately. The first inflation pipe and the second inflation pipe are connected with a micro air pump arranged inside the pillow body. A PID controller is further arranged inside the pillow body. The upper end of the pillow body attracts an elliptic support through a magnetic sheet. The pillow in simple in structure, high in intelligent degree and capable of healthily and effectively achieving the snore stopping purpose by adjusting the sleeping posture of a sleeper.

Description

technical field [0001] The invention relates to the technical field of intelligent pillows, in particular to a PID-controlled anti-snoring intelligent pillow. Background technique [0002] Snoring is a ubiquitous sleep phenomenon. It is the noise caused by the vibration of the soft palate and uvula of the pharynx when the breathing airflow impacts it. It is the cause of sudden sudden death in healthy people. Because snoring can cause repeated sleep apnea, resulting in severe hypoxia of the brain and blood, forming hypoxemia, which can induce high blood pressure, arrhythmia, myocardial infarction, angina pectoris, and what is more serious is that the time of apnea at night exceeds 120 seconds. Sudden death occurred in the early morning. The harm of snoring to human health has aroused great concern of invention engineers. There are already patents in this area. However, the productization and popularization rate of these patents are very low, and there are mainly the follow...

AI Technical Summary

Problems solved by technology

However, the productization and popularization rate of these patents are very low, and there are mainly the following problems: the one, mechanical lift pillows all have drawbacks such as mechanical wear, mechanical noise and lubricating oil dust collection; The materials are piezoelectric ceramics and polymer electrostrictive materials. The lifting system is expensive and has a small expansion coefficient. The third is that the air pump or air bag controls the height of the pillow, and does not use PID to control the PWM output. Reduce the intensity and frequency, and the pertinence and effect are poor; the fourth is the anti-snoring pillow with electric shock hands and feet.
