Dynamic air supply system and control system thereof

Abstract

The invention discloses a dynamic air supply system and a control system thereof. The dynamic air supply system consists of a fan, a chargeable polymer lithium battery, a control element of the chargeable polymer lithium battery and an air filter, wherein the fan is arranged in a shell; and the air filter is arranged on the shell. When the dynamic air supply system works, the surrounding air is purified by the air filter and then absorbed into the air supply system by the fan to form clean air with certain pressure and flow quantity and then the clean air is exhausted from an exhaust outlet. The state of the dynamic air supply system is controlled by an integrated circuit; the air quantity can be adjusted; the dynamic air supply system has the functions of displaying electric quantity in real time and warning under low electric quantity and air quantity; and the dynamic air supply system can be widely applied to dynamic air supply respiratory protective masks, positive pressure protective hoods, positive pressure protective clothing and the like.

Description

technical field [0001] The invention relates to a power air supply system, to be precise, it has the functions of fan air volume adjustment, battery power display, low battery and low air volume alarm functions, through hoses and various respiratory protective masks, hoods, and positive pressure protective clothing. Supporting use of air purification power supply system. Background technique [0002] The powered air supply system can provide clean air to respiratory protective equipment such as breathing masks and masks and maintain a certain positive pressure inside the protective equipment. The power air supply system is widely used in the respiratory protection of workers in polluted air environments. It provides users with high-level safety protection by purifying the polluted air and sending it into the user's mask, helmet or hood. Generally, the polluting gases include particulate aerosols, biological aerosols, toxic gases or steam, etc., which can be filtered and pur...

Problems solved by technology

[0006] However, the above-mentioned patents all lack the management and alarm function of battery power.

In short, although the above-mentioned domestic and foreign patents all have the basic functions of the power supply system, they all lack the real-time monitoring and abnormal alarm function of the power, air volume and other state parameters of the power supply system itself, which makes the working status of the power supply system impossible. be accurately grasped
