AI Technical Summary

Technical Problem

Existing respiratory therapy equipment has shortcomings in terms of airway modules, such as high noise, unstable airflow delivery, and large equipment size, which affect the user experience and treatment compliance of patients.

Method used

Design an air path module comprising a housing, a mounting cavity, and a buffer cavity. The air outlet of the fan assembly is connected to the buffer cavity. The buffer cavity is equipped with a bending angle and an airflow baffle. The airflow is output after undergoing at least one turn within the buffer cavity. The airflow path is optimized by supporting guides and a porous rectifier plate to achieve airflow stability and noise reduction.

Benefits of technology

It improves the stability and comfort of airflow output, reduces noise, optimizes the structural design of the equipment, promotes the miniaturization of the equipment, and makes it easy to carry.

Abstract

This application discloses an airway module for a respiratory therapy device. The airway module includes a housing with an air inlet and an air outlet. The housing also includes a mounting cavity and a buffer cavity. The mounting cavity is used to mount a fan assembly. The air outlet of the fan assembly communicates with the buffer cavity, and the air outlet is located on the cavity wall of the buffer cavity. The buffer cavity includes at least one bend angle, so that the airflow output from the air outlet undergoes at least one turn within the buffer cavity before flowing out of the air outlet. The buffer cavity guides the airflow to gradually stabilize during movement, increasing the smoothness of airflow movement and thus improving the stability of airflow output. Since the airflow requires additional kinetic energy to change its direction of travel at the bend angle, the airflow after the turn moves more smoothly and flows out of the air outlet more steadily, improving the user's breathing comfort. Simultaneously, the relative friction between the airflow and the cavity wall of the buffer cavity is reduced, lowering the noise of the airway module.
