Description
技术领域technical field

Therefore, atomization Treatment usually has a good therapeutic effect.
目前的压缩空气式雾化器，其基本原理是，通过气泵将具有较大气压的气体打入雾化器，使气体在雾化器内通过气流通道狭窄引流后，形成高速气流，通过高速气流的虹吸作用，将雾化器内的药液通过毛细管道结构的吸药通道吸入气流，并同高速气流一同激射在阻挡体(隔片)上，在阻挡体上飞溅形成雾汽，从而实现雾化效果。然而该种雾化器由于受到结构以及输出功率的限制，雾化颗粒的精细度不高，致使吸入后不易被人体充分、及时的吸收；此外，较大的雾化颗粒也不易扩散，且更容易发生凝结，降低了雾化效率。The basic principle of the current compressed air atomizer is that the gas with relatively high pressure is pumped into the atomizer through the air pump, so that the gas is drained through the narrow airflow channel in the atomizer to form a high-speed airflow. Siphon effect, the drug liquid in the atomizer is sucked into the airflow through the drug absorption channel of the capillary structure, and is lased on the barrier (separator) together with the high-speed airflow, and splashes on the barrier to form mist, so as to achieve mist. effect. However, due to the limitation of the structure and output power of this kind of nebulizer, the fineness of the atomized particles is not high, which makes it difficult to be fully and timely absorbed by the human body after inhalation; in addition, the larger atomized particles are not easy to diffuse, and more Condensation is prone to occur, reducing the atomization efficiency.
