The invention discloses two methods for removing clogging matters in an atomizer. One is a method for removing the clogging matters by adopting cleaning solution, which is to place one end of a nozzle of the atomizer into the cleaning solution, blow atomized airflow into the atomizer, so that the cleaning solution passes through a sampling capillary inner pipe at high speed and is dashed out from the nozzle of the atomizer under the action of negative pressure produced by high-speed airflow, thereby washing and cleaning the clogging matters in the atomizer at high speed; the other method is to adopt reverse blowing of the atomized airflow to remove the clogging matters in the atomizer, block an airflow channel on the atomizer, connect one end of the nozzle of the atomizer with an atomized airflow pipeline, and use the high-speed airflow to reversely wash the sampling capillary inner pipe of the atomizer from a nozzle end of the atomizer, thereby washing and cleaning the clogging matters in the atomizer at high speed. The methods satisfy the need of removing the clogging matters in the atomizer under the condition of smartly keeping the original connecting state, reduce the frequency of replacing the atomizer due to clogging damage, and ensure that the production cost is greatly reduced.
