Example one

Referring to fig. 1 to 5, the present embodiment provides an aerosol generating device, which can be applied to the fields of humidifiers, aromatherapy instruments, electronic cigarettes, aerosol therapy, and the like, and includes a first outer housing 100, a gas generating module 200, and a heater 300, where the first outer housing 100 has an accommodating chamber 110 for accommodating a solid object 111. The first casing 100 is provided with a first air inlet 112 and a first air outlet 113 communicated with the accommodating cavity 110, the gas generation module 200 is used for generating moisture, and the moisture is communicated with the accommodating cavity 110 through the first air inlet 112 of the first casing 100 and is used for wetting the solid object 111. The heater 300 is configured to heat the soaked solid object 111 in the accommodating cavity 110, so that the soaked solid object 111 is dissolved and gasified to generate inhalable aerosol, and the inhalable aerosol flows out from the first air outlet 113.

The aerosol generating device provided by the embodiment of the application comprises a first outer shell 100, an air generating module 200 and a heater 300, wherein the first outer shell 100 is provided with an accommodating cavity 110 for accommodating a solid object 111, the first outer shell 100 is provided with a first air inlet 112 and a first air outlet 113 which are communicated with the accommodating cavity 110, moisture generated by the air generating module 200 enters the accommodating cavity 110 through the first air inlet 112, and is separated out liquid to infiltrate the granular or powdery solid object 111 in the accommodating cavity 110, so that the solid object 111 absorbs water to become fluffy and is partially dissolved in the liquid, and the heater 300 heats the infiltrated solid object 111 to evaporate the liquid on the surface of the solid object 111, so that inhalable aerosol with a certain concentration flows out from the first air outlet 113 of the first outer shell 100 for human body absorption.

In the above process, the moisture can separate out the liquid and make the liquid uniformly cover the surface of the solid object 111 when passing through the accommodating cavity 110, and the dissolving speed of the solid object 111 and the evaporation speed of the liquid are increased because the surface area of the solid object 111 contacting with the liquid is large and is heated by the heater 300. When moisture is separated out of the liquid, the liquid is heated and evaporated to generate inhalable aerosol, and in the dynamic process, the solid 111 can be extracted by the continuously supplemented liquid attached to the surface of the solid 111, so that the dissolving speed of the solid 111 is improved. In addition, in the phase change process of liquid evaporation and gasification, more heat can be absorbed, so that the temperature of the generated inhalable aerosol can not be too high, and the user experience can be improved. Therefore, the aerosol generating device increases the dissolution rate of the solid substance 111 and the evaporation rate of the liquid, increases the concentration of the generated aerosol, does not increase the temperature of the generated inhalable aerosol, and improves the user experience.

The solid 111 may be paste-like solid particles or powder that can be dissolved in water.

Example two

As shown in fig. 4 to 6, the present embodiment proposes an arrangement manner of the heater 300 based on the first embodiment. The first outer shell 100 is provided with a second air inlet 114 communicated with the accommodating cavity 110;

the air entering the cavity 410 from the third air inlet 420 is heated by the heater 300 and flows into the accommodating cavity 110 to heat the soaked solid object 111.

Specifically, when the aerosol inhalation device is used, air in the cavity 410 is in a negative pressure state by artificially sucking the first air outlet 113 of the first outer shell 100, so that the air is driven to enter the cavity 410 from the third air inlet 420 of the second outer shell 400, and after being heated by the heater 300, the air enters the accommodating cavity 110 through the second air inlet 114 of the first outer shell 100 to heat the infiltrated solid object 111, so that the generated inhalable aerosol flows out from the first air outlet 113 for human inhalation. In the above process, the generated hot gas flow can increase the temperature of the liquid on the surface of the solid 111 and the fluid velocity passing through the surface of the liquid, thereby increasing the evaporation rate of the liquid. Meanwhile, the heater 300 can be prevented from being burnt due to overhigh temperature through the cooling of the flowing air.

Optionally, a heating wire is disposed in the heater 300, and the heating wire heats air after the heater 300 is powered on.

As shown in fig. 3 to 5, in the above embodiment, optionally, the aerosol-generating device further comprises an airflow sensor 600, the airflow sensor 600 is located in the cavity 410 and electrically connected to the heater 300, and the airflow sensor 600 controls the heater 300 to be activated according to the air flow in the sensing cavity 410.

Specifically, when the aerosol inhalation device is used, air firstly passes through the air flow sensor 600 and then passes through the heater 300, and when the air flow sensor 600 in the cavity 410 senses air flow, the heater 300 is controlled to be started, so that the air which is about to flow into the accommodating cavity 110 is heated, the solid objects 111 are heated, and the inhalable aerosol is generated. In the above process, the air flow firstly passes through the air flow sensor 600 and then is heated by the heater 300, so that the generated hot air flow can not burn the air flow sensor 600, and meanwhile, only when the air flow sensor 600 senses that the air entering the cavity 410 from the third air inlet 420 and then entering the accommodating cavity 110 flows, the heater 300 can be started, the heater 300 can be prevented from being started under the condition of no cooling of the flowing air, and the high temperature is prevented from being generated to cause other parts to melt.

In the above process, when the relatively cool air passes through the battery module 700, the heat of the battery module 700 can be taken away, the heat of the battery module 700 is dissipated, and the service life of the battery module 700 is prolonged; meanwhile, the cooler air is heated into hot air flow after passing through the battery module 700, the temperature of the hot air flow is higher when the hot air flow enters the accommodating cavity 110 after being heated by the heater 300 for the second time, the dissolving speed of the solid object 111 and the evaporation speed of the liquid on the surface of the solid object 111 can be improved, the concentration of inhalable aerosol is improved, meanwhile, the waste heat utilization of the battery module 700 is realized, and the heating efficiency and the energy utilization rate of the aerosol generating device are improved.
