Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] In this specification, the term "inside" refers to the side of the air supply mask that contacts the user's face, and "outside" refers to the side of the air supply mask that contacts the outside air.

[0031] The first embodiment of the present invention provides a method for adjusting the air supply volume of the air supply mask, the method includes the following steps:

[0032] S10. When the mask is in use, the breathing detection unit detects the pressure inside the mask in real time, calculates the time required for a complete breath of the user, and determines the breathing cycle;

[0033] S20. Determine the air supply volume of the air supply device according to the respiratory cycle.

[0034] In this embodiment, the pressure inside ...

Abstract

The invention relates to the field of personal protective device control methods and provides a method for adjusting the air supply rate of an air supply mask. The method comprises the following steps of (S10) when the mask is used, detecting the pressure of the inner side of the mask through a breath detection unit in real time, calculating the time required for once complete expiration and inspiration of a user and determining a breath period; and (S20) determining the air supply rate of the air supply mask according to the breath period. According to the method for adjusting the air supply rate of the air supply mask, the pressure of the inner side of the mask is calculated through the breath detection unit in real time and the breath period is determined by a pressure change, so that the corresponding air supply rate is determined, automatic adjustment is carried out and the method effectively adapts to different usage requirements.

Description

technical field [0001] The invention relates to the field of control methods for personal protection devices, and more specifically, relates to a method and system for adjusting the air volume of an air supply mask. Background technique [0002] With the deterioration of smog and pollution in the urban air, air supply masks have been favored by more and more consumers. Most of the air supply masks currently used in the market adopt a fixed air supply mode, that is, the air volume is fixed and cannot be changed with the change of the breathing frequency; some air supply masks adopt an active air supply mode, that is, the air volume decreases when exhaling, and the inhalation The air volume increases when the air is out. But for the sports crowd, its breathing cycle changes greatly, so many different air supply volumes are required, and the existing air supply masks cannot fully meet the needs. [0003] Therefore, there is a need for a new method for adjusting the air supply...
