no. 1 Embodiment

[0046] Optionally, as in figure 1As shown, the first specific embodiment of the present invention, when the volume of the atomizer of the present invention is small, the air intake port of the air flow channel 104 is provided with a draft fan 70, and the draft fan 70 is connected to the mounting base 10 On the end 101 , the induced draft fan 70 is used to rotate under the action of the external airflow, so as to accelerate the external airflow to enter the atomization chamber 102 after passing through the air channel 104 . The design function of the induced draft fan 70 can quickly introduce the external air into the atomization chamber 102, reduce the mist temperature of the medicament steam, reduce the damage that the medicament steam may cause to the epidermal cells of the respiratory tract, and at the same time quickly introduce the medicament steam into the patient's body, reducing the The vapor condensation of the medicine vapor in the channel due to too long time causes...

Abstract

The invention discloses an oral suction type nebulizer. The oral suction type nebulizer comprises an installation base; a nebulization cavity used for containing a medicament to be heated for nebulization is arranged in the installation base; a heating component used for heating the medicament to make the medicament to be nebulized into medicament steam is arranged in the nebulization cavity; theheating component is connected with a controller used for controlling acting of the heating component; the installation base is detachably provided with a suction nozzle communicating with the nebulization cavity, and a cooling and dispersing column is further arranged between an air inlet end of the suction nozzle and the nebulization cavity; the cooling and dispersing column is used for evenly dispersing and cooling airflow entering the suction nozzle from the nebulization cavity; an airflow channel used for introducing external airflow into the nebulization cavity is further arranged in theinstallation base, so that when a patient sucks the suction nozzle to make a negative pressure environment formed in the installation base, the external airflow enters the nebulization cavity throughthe airflow channel, and the medicament steam is brought away from a liquid surface so as to form an aerosol containing the medicament, and then the aerosol enters the body of the patient after passing through the cooling and dispersing column and the suction nozzle under the action of the external airflow in sequence.

Description

technical field [0001] The invention relates to the field of atomizing devices, in particular to a mouth-breathing atomizer. Background technique [0002] As the global environmental pollution continues to intensify, the number of patients with respiratory diseases continues to increase, especially the outbreak of infectious diseases such as SARS and the new coronavirus, which seriously affects people's life safety and normal life. Nebulization is used to treat respiratory diseases represented by new coronary pneumonia is a very effective treatment. The principle of this treatment method is to use a medical nebulizer to atomize the therapeutic liquid, enter the patient's lungs through the patient's spontaneous breathing or mechanical ventilation, and be absorbed by the patient's body to achieve the purpose of treating respiratory diseases. Among them, the performance of the nebulizer is very important. The size of the mist particles determines the settlement position of the...
