Abstract

The invention belongs to the field of filter detection, and provides an aerosol generating apparatus. The apparatus comprises an aerosol liquid storage tank, at least two nozzles, at least two electromagnetic valves, a compressed air pressure sensor, a flow nozzle pressure difference sensor, a fan box and a control part, wherein the compressed air pressure sensor is used for testing the pressure of compressed air; the flow nozzle pressure difference sensor tests pressure difference between two ends of a flow nozzle; the control part is in communication connection with the compressed air sensor, the flow nozzle pressure difference sensor and the electromagnetic valves. The control part calculates the number of the electromagnetic valves needing to be opened according to the pressure of thecompressed air and the pressure difference between the two ends of the flow nozzle so as to control the opening of the electromagnetic valves. Due to the fact that the number of the opened electromagnetic valves can control the generation intensity of aerosol and the number of the electromagnetic valves needing to be opened can be rapidly calculated, the particle concentration of the front end ofa detected filter can be stably and rapidly achieved, and the advantages of stablity, rapidness, convenience to use and visuality are achieved.

Description

technical field [0001] The invention belongs to the field of filter detection, and in particular relates to an aerosol generating device. Background technique [0002] When testing the filter, a certain concentration of aerosol is required at the front end of the filter. Aerosols are generated by aerosol generators. In the prior art, aerosol generators generally use compressed air or heating to generate aerosols, and adjust the amount of aerosol generation by adjusting heating power and compressed air flow to adjust the aerosol concentration. . The compressed air pressure and the number of nozzles will all affect the amount of aerosol generation, and the aerosol generator with thermal generation is also affected by the heating temperature. Therefore, in order to make the aerosol at the front end of the detected filter reach a certain concentration, it is necessary to use a particle counter to detect, and then adjust the aerosol generator according to the detected concentra...
