Novel nebulizer with reflux structure

Abstract

The invention discloses a novel nebulizer with a reflux structure. The novel nebulizer comprises a bottle body for holding liquid medicine, the upper side of the bottle body is connected to a seal cover and a fixed block, the fixed block is internally provided with an airflow channel and a nebulizing chamber, a liquid accumulating slot is disposed at a bottom middle part of the nebulizing chamber,a reflux pipe is disposed under the liquid accumulating slot, a connecting pipe is movably inserted on the nebulizing chamber, the seal cover is internally equipped with a drain pipe, the upper end of the drain pipe is communicated with the airflow channel, one side of the drain pipe is equipped with an impact plate, and the lower end of a regulation block is provided with a flow velocity port. The novel nebulizer provided by the invention regulates the nebulization effect through up-and-down sliding of the regulation block, also is equipped with the reflux structure and the like, so that nolarge amount of liquid accumulates in the nebulizing chamber, connecting pipe and other cavities communicated with the mouth, the risk of mis-suction of liquid cannot be caused, and while the drug application precision is improved, the waste of liquid medicine is also reduced.

Description

technical field [0001] The invention relates to the technical field of atomizers, in particular to a novel atomizer with a backflow structure. Background technique [0002] As we all know, medical nebulizers are mainly used to treat various upper and lower respiratory diseases, such as throat tumors, pharyngitis, bronchitis, asthma, cough, fever, pneumoconiosis and other diseases that occur in the trachea, bronchi, alveoli and chest cavity. The important link in the tool is the atomization of the original medicine. The amount of atomization and the size of the particles after atomization of the original medicine directly affect the therapeutic effect. The existing traditional nebulizer atomizes the medicine liquid during the atomization process. It is difficult to control the speed and particle size of the atomized original drug, which causes inconvenience in use; and the nebulizer is often used to treat children's respiratory diseases. Compared with adults, children have hy...

[0002] As we all know, medical nebulizers are mainly used to treat various upper and lower respiratory diseases, such as throat tumors, pharyngitis, bronchitis, asthma, cough, fever, pneumoconiosis and other diseases that occur in the trachea, bronchi, alveoli and chest cavity. The important link in the tool is the atomization of the original medicine. The amount of atomization and the size of the particles after atomization of the original medicine directly affect the therapeutic effect. The existing traditional nebulizer atomizes the medicine liquid during the atomization process. It is difficult to control the speed and particle size of the atomized original drug, which causes inconvenience in use; and the nebulizer is often used to treat children's respiratory diseases. Compared with adults, children have hyperactive habits, so children use nebulizers When the angle of inclination is large, the nebulizer may be tilted, so that the end of the suction tube immersed in the liquid is exposed to the outside of the liquid, and when the angle of inclination is large, the liquid medicine in the bottle will flow back out and flow directly to the patient's body through the pipeline. In the mouth, this will not only cause the risk of aspiration, but also increase the discomfort to the patient, so we propose a new nebulizer with a backflow structure
