Air source device and portable breathing machine

Abstract

The invention discloses an air source device and a portable breathing machine, an air source assembly comprises a shell assembly and a motor assembly arranged in the shell assembly, an impeller assembly is fixedly installed at the output end of the motor assembly, an air duct assembly is arranged between the impeller assembly and the motor assembly, the air duct assembly is coaxially and fixedly installed on the motor assembly, and the air duct assembly is fixedly installed on the shell assembly. A gap is formed between the impeller and the impeller assembly; a first airflow channel and a second airflow channel which communicate with the impeller assembly are formed between the air duct assembly and the shell assembly, and an inlet of the first airflow channel and an outlet of the second airflow channel are distributed in the circumferential direction of the air duct assembly. The shell assembly is provided with an air source inlet and an air source outlet which are communicated with an inlet of the first airflow channel and an outlet of the second airflow channel respectively. The internal structure is highly integrated, miniaturization development of breathing machine equipment is better facilitated, meanwhile, through structural optimization, the air inlet direction and the air outlet direction are located on the same plane, and meanwhile air duct noise is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of ventilators, in particular to an air source device and a portable ventilator. Background technique [0002] The ventilator is mainly composed of an air source device and a control device. The air source device is the core component of the ventilator, mainly including fan components. The control device mainly includes a control circuit, flow and pressure monitoring, control buttons, display screen, power supply, tube. Roads, humidifiers and masks, etc. In order to improve sleep breathing, the application of home ventilators is becoming more and more popular, but when traveling, traveling, etc., due to the limited luggage space, the ventilator is required to be more miniaturized for easy portability. As ventilators become more and more miniaturized (smaller in size), the difficulty of how to integrate the fan into a small space also increases. Especially the air source device with traditional structure ad...

AI Technical Summary

Problems solved by technology

Especially the air source device with traditional structure adopts the existing turbo blower, the air intake direction is set along the circumference of the turbo blower, and the air outlet direction is facing the axial direction of the turbo blower. The two are not on the same plane, but are located in a three-dimensional space. , not only the volume of the fan is larger, but also the noise is too large
